No Picture on Your Plasma TV

Have you turned on your plasma TV to find that you have sound but no picture? Or maybe not even any sound either? Well, my friend, rest assured that it’s not just you. This is actually a fairly common problem with plasma TV sets. No matter the brand or the manufacturer, your picture is likely to disappear at some point. So, why does it happen? What causes this problem? Read on to find out why this happens and how to fix it—that is, unless you yearn for a return to the old-timey days of sitting around the radio!

Plasma TV Problems? How Your Plasma TV Works

The boards of a plasma TV.

The boards of a plasma TV.

Most plasma TVs are made by three manufacturers: Samsung, LG, and Panasonic. What makes them different from other TVs is the plasma flat display panel (PDP), which uses ionized gas (or plasma) to produce the images on screen. The first thing you’ll want to check is whether the PDP is cracked, which could cause the gas to escape and render the set pretty much useless.

A PDP also comes with a number of electrical boards including:

  • Y-buffer (sometimes in two parts, a Y-upper and a Y-lower).
  • Y-sustain. Names vary by manufacturer: Samsung calls it a Y-main while Panasonic calls it an SC board. You can find the Y-sustain board on the left-hand side of the screen when looking at it from behind.
  • Z-sustain. Names again vary by manufacturer: Samsung calls it an X-main while Panasonic calls it an SS board. You can usually find the Z-sustain board on the right-hand side of the screen when looking at it from behind.
  • Control board. Sometimes called a T-con (though not to be confused with LCD T-con boards). The control board is usually found underneath the main board.
  • X driver. Often integrated into the control board or fitted onto it.
  • Power supply
  • Main board/AV board/Tuner board. This board has all the input connectors, antenna, etc.

Tools to fix your LG, Samsung, or Panasonic Plasma TV when there’s no picture.

  • A Digital multimeter. NOT an analogue one.
  • A Phillips head screwdriver.
  • Optional: an oscilloscope with a minimum of 400V inputs and a 10x probe.

WARNING: Plasma TVs have a very high voltage—in excess of 380 volts on some connectors, which is the same amount of electricity that doctors use to defibrillate a heart! So, you should ABSOLUTELY not touch any of the TV’s electrical components either while it is still plugged in or running. If you do not have much experience doing electronic repair work, you should hire a professional to do the work for you.

No Picture on Your LG, Panasonic, or Samsung Plasma TV: Identifying the Problem

Check to see if there’s sound when the TV is plugged in. If there’s no sound either, then it’s likely there’s a problem in the power supply. If, however, there is sound and the set responds to commands from the remote and side buttons, then it’s likely a problem with Y- or Z-sustain.

If Your Plasma TV Has No Picture and No Sound:

Here are the steps you need to take in order to troubleshoot your malfunctioning plasma TV.

  1. Turn off the TV and unplug it from the wall.
  2. Wait 5 minutes so that the capacitors are discharged.
  3. Unplug the connector going into the Z-sustain and then plug the TV back in.
  4. Check for sound. If there’s sound, then the problem is with the Z-sustain. If not, then:
  5. Unplug the TV and wait another 5 minutes. Then disconnect the Y-sustain and re-connect the Z-sustain.
  6. Plug the TV back in and check for sound. If there’s sound, then the problem is with the Y-sustain.

If the problem seems to be coming from the Y-sustain, you also need to check out the buffer. To do that, follow these steps:

  1. Unplug the TV and wait 5 minutes.
  2. Remove the buffer and see if you get a picture with sound.
  3. If your TV has two buffers, disconnect the upper buffer and see if you get a picture on the lower screen.
  4. Then disconnect the lower buffer and see if you get a picture on the upper screen.
  5. If, after removing one of the boards, you can see a picture, you know that the removed board is the problem.

You should also check out the video below, which can guide you step-by-step through the process of repairing your plasma TV.

Plasma TV Has Sound but No Picture:

If your plasma TV has no picture but the sound still works, then the problem is usually due to a faulty Y-sustain. If you’re lucky, it could just be a blown fuse, which is easily replaceable. But if not, you might have to replace the entire Y-sustain. To test the fuse, follow these steps:

  1. Unplug the TV and wait 5 minutes for the capacitors to discharge.
  2. Set your digital multimeter to 200 ohms.
  3. Touch the red and black together. The reading should be around 0-2 ohms.
  4. Connect the probes on each end of the fuse with the multimeter. If it reads “1” on the left-hand side, or “OL,” then the fuse is blown. If you get the same value on both sides, then the fuse isn’t the problem.

If the fuse blows again, you will need to repair or replace the Y-sustain. (It’s often times much easier and cheaper to replace the board than to fix it—unless you have a lot of experience doing these repairs yourself).

George on September 01, 2018:

My 51” Samsung 3D Plasma TV model PN51D490A1DXZA was showing vertical lines on the screen for a couple of years. It’s our extra TV in the basement so we never bothered to fix it. The other day I heard a loud popping sound as I was watching a program then the screen went black. The audio from my dish still comes through fine and I can change channels to “listen” to a program but with no picture. What do you think the cause might be?

Linda on November 14, 2017:

WHERE do you get at Y Buffer. Is it show ecl expensive..

Have a 42in Samsung Plasma.

Don t have model # at time.

Tv has sounds channel changes light on front..when turn on..2006 tv.

Can it be fixed.

Greg Eaglin on October 04, 2017:

I have a 60 inch Samsung smart TV that I purchased in 2014 (Model PN60F8500AFXZA); the TV is connected to an AV receiver/external speakers and cable box. Several days ago, the picture and sound began to disappear intermittently; the picture and sound would return after several minutes. This on-off interval has been increasing and now the picture/sound may return after the unit has been unplugged for several hours. Do you think I have a power supply issue or may the issue be something else?

Sam on April 24, 2017:

I have a Panasonic Plasma Model TC 54PS14, where the picture and sound just died while watching a movie. Then came the 7 blinking red light. I googled it and some say it's probably the SC board. So what do you think?

Thank you for your reply.

eke5s on April 14, 2017:

My LG 60PK750 plasma screen is blank. When I turn it on I hear the normal click I have always heard but now nothing shows up on the screen and I have no sound. I tried to change the inputs with the remote and tried the menu button on the remote and nothing shows up when I push those buttons. In addition, I also have the digital audio connected to a sound bar. Before when I turned on the tv the sound bar would come on automatically a few seconds later. Now when I turn the tv on, the sound bar does not come on by itself. Please help.

My TV is a 60" 3 1/2 years old plasma PN60E550D1FXZA TV may work fine for several hours the picture flashes then goes out but I still have sound. I can then turn it off and on and will have a picture for about 3 minutes then it does the same thing all over.

NapoleonTuazon on September 02, 2016:

Hi my Samsung Plasma 43 inch made really loud popping sounds today and now no video or sound. I brought it to a trusted technician since it's out of warranty since I have it for 4.5 years the technician advised me to replace both YSUS and ZSUS . Per your recommendations this type of issue is related to the YSUS or Y Sustain board.

Should I replace the ZSUS also?

Harees on August 12, 2016:

Dear Sir,

All of a sudden, my 42" Samsung Plasma TV( model- PS42B430) has created a problem,

I have an 60PV450-UA LG Plasma,

For the last 2 months my 60" TV has been having an issue with light colors (usually when in a menu of sorts) where it flickers a bunch of random colors. I procrastinated fixing the issue as it was still working and wasn't big enough issue at the time to fix. 2 nights ago we were watching a movie on netflix and it worked great. next morning we turned it on and there was sound but no picture, the screen normally lights up the tiniest bit before displaying the image on the screen, but didn't do it this time.

So i did some digging and found it was a common issue with the screen flickering, solder points for the coils on the ZSUS were cracked, so i got out the soldering gun and solder and fixed it up, in hopes to kill 2 birds with one stone (flickering image along with blank screen when turned on) ... unfortunately that didn't work out. i've seen other people mention the exact same thing with no answers to the problem. i payed $2,000 CAD for my 60" LG Plasma in 2011. i refuse to give up on it. I hope someone has answers to the black screen specifically, i don't have much money these days and would like to solve this issue directly. i will be checking the fuses as suggested by others to clarify the fuses are fine, I'm hoping i don't need a new YSUS and Y-Buffer..

Jamieaclarke on July 13, 2016:

Hi I have a 60PX950-AA LG plasma ,

I have sound when I disconnect the YSUS board and the same when I disconnect the ZSUS board, would this mean it's the YBuffer?

Jamie on July 13, 2016:

I have a lg 60px950-aa serial number 011kcxm1g122 and I have sound but no picture when I disconnect the ysus board and the same when I disconnect the zsus board could this mean it's the y buffer?

Doug on June 10, 2016:

I have a Visio MP50 Plasma. The machine stopped powering up. I found a blown fuse and replaced it. It powers up now but I get no picture. The screen is not dark and I get audio but no video input. I swapped HDMI inputs and cables but still no video input. I have checked all fuses. Where should I check next? None of the capacitors look deformed. to provide assistance.

sccu1971 on May 31, 2016:

Hello, I have the symptoms of no picture with sound and acocording to your troubleshoot I would need Ysus board. However some forums recommend that you change the y buffer boards also when Ysus is replaced. I'd rather be confident the first time but not sure what is necessary for my specific issue. If you have the time, however, here is my symptoms and numbers I recorded with little help from other sites but I never get a reply.

No Picture, but Still Have Sound - Samsung Plasma PN60E550D1F

History: Past year found that after TV has been ON an extended period will have no picture if we turn OFF and then back ON. We would have to wait in the beginning maybe 5 minutes but up until now a year later, we waited 20-30 minutes. However, we would always have sound.

Even today I get sound but no picture at all... Even waiting next day.

I went through a forum on this site for exact same model and similar symptoms but the other guy had no voltage when checking Vs and Va.

Here is what I found answering the other forum questions:

1. According to voltage sticker inside: Vs: 211, Va: 57, Vsc: -198, Ve: 98

2. Checking voltage at Vs after going from STBY to ON: spikes to 211V then within 1 min voltage drops to 10V

3. Same thing with Va: spikes to 57V then rapidly drops to 0V within 15 sec.

4. LED is blinking 5-sec ON, 1-sec OFF.

5. Disconnected Y Sustain and X Main from each other and from power supply then repeated step 2 and 3 with results equal to zero volts for both Vs and Va.

6. Found online instruction from shop testing power-on sequence and logic board.

6A. While in STBY mode, cycle power ON and check Ps ON and Vs ON voltage. Result:

Ps ON: STBY = 3.3V, Power ON = 0V

Vs ON: STBY = 0V, Power ON = 3.3V (spike) then immediate drop to 0.0V.

I didn't get any further than that but decided to pull the PS, Y sustain and X main the next day to inspect my best ability for cold solder joints, but all appeared to look good when carefully moving components on opposite side. no swollen caps either.

I'm not sure but it looks like PS is putting out voltage briefly but maybe the fault is not allowing controller to fire it up (Safety mode?). Maybe it's still good?

I'm now at the point where I can't find any further troubleshooting knowledge online unless someone out there can help me further? I tried to find a free fast track or service manual out there but no luck also. I appreciate you taking time to read and if you have time to spare me id be greatly appreciative. Thank you

PS: I can add photos if needed.

Kind Regards,


Rochester Hiils, MI

Chris on May 19, 2016:


I have a Samsung LE40R73BDXXEU - when switch on works great for about 20mins, then the picture stops, however, the sound stays on. You switch TV off, wait for about 2 hours and switch on and the cycle repeats its self- do you have an idea of what the problem could be.

Kind regards


Jg Lapointe on April 30, 2016:

I have a Toshiba 50 inches plasma 50hp66 ( almost 10 yrs old). The screen is white as white clouds. I see the picture very lightly behind the white. The sound is good. Before the screen became white, there were some colored shades on the faces of people. Any hint??

Jamie Beedie on January 15, 2016:

Hey omendata (or anyone else who could answer). I have an LG 60PA6500 and am trying to troubleshoot picture problems. Would you happen to know what 2 pads I would need to short on my logic control board for this set to get the test patterns (and verify PDP is still good)?

Here's the long version. Originally had sound and no picture. Found top y-buffer, 2nd chip down shorted. Removed from tv and checked lower y-buffer (no shorts). Turn tv on, lower half of screen full of all sorts of colored pixels moving around (connected to video source and am guessing they're moving with the video). I've purchased used componets off ebay (supposedly 100% here....) and replaced the y-sus (same crazy amount of colored pixels across bottom...can't make anything out on screen)....replaced z-sus (same resulting colored pixels covering entire lower half).....I've even purchased another logic control board (same resulting colors.....but get a different D101 blink code on the logic control board). I've got an upper y-buffer coming today so that now maybe I can have an entire full screen full of crazy colored pixels to look at until I can figure out what this problem is. By bypassing the main video board by shorting those 2 pads on the logic control board (and hopefully getting a test pattern....I'm guessing do this with it turned off and it will turn itself on) I can verify my PDP is still good (which has me worried getting all this crazy looking pixels all over the screen) and perhaps tell me that my main video board is bad???? Am I crazy or this sound correct?

Now, just gotta know which two pads to short to get that pattern....

Stevie on January 13, 2016:

I have a Sony KE42M1 Plasma TV with sound but no picture. Picture will sometimes return after sitting unplugged for long periods; however, if the TV is turned off picture disappears again. Any recommendations would be greatly appreciated!

John on January 08, 2016:

I have a model PN60E530A Samsung plasma TV. If I shut it off and try to turn it back on within 5 to 10 minutes all I get is a completely black screen with sound. The waiting time seems to be getting longer now. It's now about 15 minutes. It's like something has to cool down before you get a picture. Any ideas?

Steve on November 27, 2015:

HI. I have a 2.5 year old Samsung 60 inch plasma. It has started going black, but sound remains. When this happens, I can usually get it back by turning off the TV and turning it back on. What do you recommend???

My Plasma TV has sound but no picture. May have just a blown fuse. My question is where is the fuse located?

Debbie Kinder on September 04, 2015:

I have a 3 yr old 40" plasma Pansonic that I had repaired once & now doing the exact same thing again, no picture, powers on, no sound but I do have sounds from the TV off as I am using the sounds thru a Bose surrounds systems and can hear the cable broadcast but cannot see anything , cannot power off the TV must unplug the TV. Any suggestions

Talla on August 24, 2015:

greetings sir please we have a 52 inches plasma samsung tv at power on it flashes an image on the screen with a sound then goes off with the screen dack. We have tested the power supply and found out that there is 5v and 3v but no 15v . please what can be the problem we will be glad if you can help us out thanks.

omendata on August 05, 2015:

Unlike the old days tvs are like computers - you jus swap in a new board to replace the faulty one - the difficulty comes in pinpointing which board is faulty - After reparing my LG Plasma i just bought replacement boards for every part in my tv in case they arent available in the future and it still cost less than it would have to put it into a shop.

I am a computer electronics engineer but i had never opened up a plasma tv until mine went a few weeks ago - 2 weeks of researching and watching youtube videos and I now understand how the things work - its all on the internet - if you have the requisite skills and the internet you need never employ a tradesman again - In 30 years i have only had a tradesman out once , the rest my father taught me (car mechanics, plumbing, building work - i've repaired and learned most of it from google) - its all there and the parts on ebay or shopjimmy - then there are the forums where the experts hang out - is the best imho for elecronics repairs - all it takes is effort and time there are no quick fixes.

Susan on August 04, 2015:

Hi, I went to turn on my LG plasma this morning, the t.v went on however no screen and no sound, took out the plug, removed from t.v fur a few hours and it's still not went on, do you have any idea what the problem is and if it's fixable myself, thanks.....

omendata on August 03, 2015:

Haha i know how it is im unemployed myself so have to fix everything myself - fixed my car twice thi syear , washing machine , cooker - good thing about being skint is you are forced to learn new things out of necessity.

First remove the lvds cable from the control board to the main board.

There are two point near resistor p104 they are the only places on the control (logic) board you can bridge. If you get test patterns on the screen then you are halfway to fixing your tv as it means the most expensive part the screen is ok and the buffers. Patterns on screen also mean the main logic board is ok.

Which means z-sus, control board, y-sus are really all that is left to test. My problem was the z-sus and blown psu but its all sorted now and cost less than £50.

Watch what you are doing swapping boards - if your y-buffers are gone and you plug in a new ysus board you can blowe the new ysus board.

You really need a multimeter and to measure the output of the psu labelled vs,va and standby - 200v,93v,5v respectively.

Then measure the actual vs,va and standby on the boards that use them y-sustain , z-sustain, control board.

You can remove the y-buffers to test em but first thing i would do is check and see if you can get a picture with the two test points on the control board.

Jeremy on August 03, 2015:

Omendata, which spots do you jumper with a paper clip? I'm low on disposable income, so the tv is just sitting apart currently till I can find the next board to swap for cheap. I did the x and y sus. Next I'm going to try the main power board and logic board. And maybe get some extra ribbon cables to test if cables are bad.

omendata on July 31, 2015:

Yes Sarah exactly the same happened to me.

Check youtube

My fix was to resolder the top 22ohm 5 watt resistor.

Actually i replaced both as the top one had blown but best to replace both but as you are getting power it soundslike your psu is ok - what happens when you press the power button on the remote does the tv come on or do you hear a click and the tv switches off. If it doesnt switch off your power supply is liable to be ok.

Then the tv powered on ok.

Unofortunately no pic but sound.

Its either your y-sus board and/or y-buffers or in my case the z-sus board had gone - got some help with a new board and hey presto fixed.

Contrary to popular belief tv is now like a pc and swapping boards is cheap way to do it - zsus board on ebay £19.99.

Save yourself a fortune as long as you are familiar with removing screws and plugging cables.

There are videos on youtube showing you how to test each board - y-buffers etc - remove the y-sus board and see if you get a picture - if not then remove zsus and reconnect y-sustain board.

You can bridge two points on the control board with a paperclip and if you get a picture your control board is ok.

Dont give up its a good tv and its easy to fix as long as you know how - you could probably buy every board for it and replace them all and it would still cost less than a shop will charge.

Sarah on July 31, 2015:

LG plasma 50inch. Model 50PN6500 The TV is not even 18 months old I was watching it and the picture just went off there is still sound but the screen is just black any help would be awsome thanks

omendata on July 29, 2015:

check the voltages on the ysus and zsus boards test connections and the outputs of the psu check if va vs and standby are at correct voltage.

Hurl3yboy22 on July 29, 2015:

50PC5D 50" LG Plasma TV

Plugged in, slight clicking noise on the PCU board.

I noticed that D1 and D2 on the Controller board aren't lit. Faint single blink of the led on the AV board.

Doesn't look like any caps bulging or blown but could be wrong.

Screen turns on to only a dark fuzz, no lines, no sound.

All voltages check out on the power fed connectors, and I've checked a few resistors but not sure of the (O)s of each.

Any thoughts?

omendata on July 27, 2015:

Y sustain board maybe - there are so many possibles.

Sounds like faulty capacitors!

Thisblows on July 26, 2015:

I have a Samsung model #PN64E533D2F.

Sound is there, no picture. My wife would turn the TV on and off several times before getting a picture. Now, we just get sound.. Anything would help. Thanks..

omendata on July 25, 2015:

Hi I have a similar problem to Jeremy.


Problem initially was power supply - common issue with LGPK range - 22ohm 5 watt resistor (top one) always goes so replaced both and tv now comes on. No need to replace diode or smps transistor that also sometimes go pop!!!

How depressing - Sound but no video.

Are you sure about z-sus test as i removed it and there is still sound but no video. Z-sus seems fine to me electrically.

Cannot change channel or input selector it stays on hdmi 1.

Going to do a test of the y buffers - ordered a new y-sus but didnt fix the issue.

Removed buffers individually and power on - no result.

After talking to repair guy he reckons its the t-con.

Any ideas before i get the oscilloscope out?

eliasp9 (author) on July 11, 2015:

Hi Tom when the tv shuts off and the blue light comes on does it blink if so how many time?

Tom R on July 04, 2015:

I turned my Pioneer Plasma PDP 5060 HD TV on and I get a message on the bottom that says "starting please wait" and "Plasma display" I have unplugged but no change. After about 5 minutes it shuts offand light on control box blinks blue continously. I can get the "home Menu to come up so picture is still there. Any suggestions?

Lisa W on July 03, 2015:

I have a 50"LG Plasma TV about 4 years young. Anyway, I was watching it, then suddenly it went off. It is connect with the surround sound through my DirecTV box so I still hear the TV. I disconnected it from the power in the wall for the entire night but nothing. The power light in the front does not come on....what should I do? Did it just play out and a new one is needed! If so, can u recommend a brand for my next investment, if necessary?

Jeremy on June 19, 2015:

ive double and triple checked the connections. I don't have cable, just smart boxes. I wouldn't be able to tell if it changes channels. Unless there's an easy way you can think of.

alsoto007 on June 16, 2015:

Hi, I have a Samsung Plasma model # PN60E530A3FXZA version # TS02.

Occasionally, when the TV is turned on, I get sound with no picture. The picture usually returns after powering off the TV and waiting 5-10 minutes.

While the TV is on with sound and no picture, I can change channels.

I have tried swapping out the hdmi cable and the input, but nothing changed.

Please advise. If parts need to be changed, please advise on where to purchase.



eliasp9 (author) on June 14, 2015:

Hello Jeremy ok can you change channels while on no video? Also please check all connections on connectors from the Y board and X board thank you.

eliasp9 (author) on June 14, 2015:

Hello Daniel56 sorry to hear this about your tv set. The problem that you are having is called Mal discharge this could happen due to a bad Y sustain drive board, a bad connector or connection( less likely), a bad Y sustain board or a faulty control board. The voltages on each one of this boards would have to be measured and tested to see which one is faulty. Once the faulty board is discovered it will have to be replaced, thank you for your question and hope this helps.

Jeremy on June 12, 2015:

I have a Samsung pn60e530 and its having the issue of sound, but no video.

So far, I have purchased an x sustain and a y sustain board that are '100% tested and working' and it still hasn't fixed the problem.

Any ideas?

eliasp9 (author) on June 11, 2015:

Hello Mary thank you for the question. Ok the problem is located on your Y sustain board. The IPM in the board is faulty, due to a component that has giving up. The cost really depends on the tv repair shop that you take it to couldn't really say it all depends. But that it can be fixed yes it can.

Mary de Stefano on June 09, 2015:

Pioneer Plasma TV PDP 6010ED - picture goes black every 15-20 minutes. I must turn on TV again to retrieve the picture. Can this TV be fixed? Range of costs please.

eliasp9 (author) on June 07, 2015:

Hi PJGMAG questions. How long have you had the tv? Also when you turn on the unit can you hear anything, like if the unit is on? Does it have a light in the front of the tv that tells you if the unit is on or off? I am trying to pin point if the tv turns on but no picture or sound or if the unit is not doing anything at all thank you.

Panasonic TH-42PZ85U started cutting out for seconds at a time such that I thought it was the cable signal (no picture no sound). Then finally went blank for good. Checked another TV to confirm it was not the cable signal. Any idea what went wrong and if I can fix it?

We have a 50" Panasonic plasma TV (probably 6 yrs old at least). Once every so often it would not turn on, but after a few times of turning on and off it would come on. Today it does not come on. No sound or picture. Any ideas? Thank you!

I have an LG 50PC3D that has a flashing picture at times but the sound continues. For some time prior to this I had noticed that the picture would go slightly blurry and then refocus every 10-15 seconds. What do you recommend for a fix?

I have a LG 60PA6500. It has no picture and no sound. When it's plugged in the indicator light comes on and never changes. Screen barely glows a little. Hitting the power button does nothing. I've tried unplugging for a while. Holding the power button. Even replaced the power supply board. Still no luck. Any suggestions?

i have a 42LG Plasma' , and when it get's Hot' , the pic goes dark, only sound remain..., i think it's the Y-sus board..., any ideas ?

Paul on December 02, 2014:

I have a vizio 57 inch plasma 8 years old, and have been having difficulty turning it on and getting the picture to come on. It has sound however I either have to turn it on and let it almost if you will warm up, then turn it off and on, to get the white flash which means picture comes on. Typically if we don't let it warm up for at least 5 minutes and do the on off thing, we have to click on off for like a minute before we get the white flash which means the picture will show up on the screen right after.

Does this mean the tv is coming to the end of its life span or do you have an idea what could be causing this that I can repair.

Thanks for your time.

I bought 109.22cm (43) H4900 Cricket Mode 3D Plasma TV on 1st April 2014 for FIFA world cup 2014.

After six weeks (May 20-2014), try to power on the power red light blinks, but does not power up the screen need to click several times to turn it on. I called Samsung Customer Care one technician came and take the power board inside the TV to service center.

First weak they told me to replace power board and took the TV. Second week they told power board was replaced and needed to replace mother board. Third week they told mother board was replaced and needed to replace display Panel.Every day i called the Tech for my TV ,he replied he would call back in 5minute.But he never called me.This process continued for two weeks.Once I visited the Service center he told me about refunding.But now i cant contact him because he put my number in call reject list. (His no is 9946006499 Samsung Service Center Pathanamthitta). Anyway World cup is on half way stage my NEW TV is in Samsung Service Center. PLEASE give me my money and sorry for buying a SAMSUNG TV I will never repeat this.

For a small common complaint they replaced motherboard, display panel,and hold my TV for 30 days,and now he want 10 more days.

Some poor brand name digital LCD television sets such as Technika; Bush and even Samsung, are often apt to malfunction well before their actual estimated life-span. The pixilation issues such as loss of sound or picture, are significantly more to do with the very poor standard of technology that goes into making these TV's rather than it be a fault with external sources - once leads and Ariel's are replaced, and there is still no picture or sound, or both; you can guarantee it is precisely due to the fact that, the various components such as HV X main circuitry boards; transistor parts etc. all come from various countries before being installed into a new TV set and purchased by retailers at low-price stock prices. It costs approximately 10 pence or less for a HV/X Main card with all the circuitry applied in a foreign factory, yet to buy one in the UK, obviously will cost significantly more, and you run the risk of electrocution if you attempt to service your own television by replacing the old card for a new one, if you have little or no experience in the field of electronics and where the advice in the article is not recommended. It is far better to purchase a manufacture refurbished one at half the cost of a new one, if it comes with at least a 12-month guarantee as I have done. In addition, no TV set, including brand-new ones are entirely new - they are often refurbished in shops and sold as new because many are ex-display; customer returns - retailers simply refurbish and sell them at brand-new prices, and why if you are on a tight budget, recommend simply buying one pre-owned and refurbished from a retailer that offers a year's warranty.

it should be around if your handy and know about capacitors, how to measure them, read them with the ohm meter etc.... it should be around 50 bucks or so depending on the service manual, where you get it from and the repair kit for your TV. If you are buying the whole ysus board I suggest trying ebay see if you can get an original board from there if not do a google search see if you can find it there, remember to get a service manual for your tv s make and model very important thank you.

christopher on May 05, 2014:

my toshiba plasma tv has no picture or sound, when you push the power button it flashes red

jang342 on November 23, 2013:

my led lcd devant 40 inch tv is less than 1 year old. lately, it has been intermittently shutting off the picture every 15 to 30 seconds but sound is okay. this happens mostly in the evening. then it becomes more frequent such as every 2 to 3 seconds and even less. in the morning, it operates sometimes normally, but you can not expect it to be trouble free all the time. i dont like having to guess when my tv set is okay and when it will not be. when i have time, i will bring it to the repair shop. in the meantime, i would welcome any suggestions, hints or advice.

Glen E. on January 18, 2013:

Well, this is a great article, and the Y-Sustain board is a great answer, but, another common reason for a Plasma TV to give sound but no picture is for one of the buffer boards that are connected to the Y-Sustain board to fail. A failed buffer board will cause the same symptom, and replacing the Y-Sustain board will not fix the problem if you have a failed buffer board.

eliasp9 (author) on November 24, 2012:

Hello kay sorry for the late reply to everyone that commented. Ok kay if you bought a new tv i am very happy for you hopefully led, hdtv something like that, if you didn't just be careful it will give you the same problem again an at the end of the day you ll spend more to fix it then the new set.

kay on November 02, 2012:

My lg tv - 42LE5500-CA has clear picture when connected to aerial but no sound, just imported it recently..No other connection other than power & aerial Help

Ronnie on January 27, 2012:

Well the article sort of speaks about TV's that are bound to break down over time, which is quite understandable. But I am sitting down here with a Samsung PDP43D490 which is a mere 27 days old as of today with the same problem. The only difference is there is neither sound nor video. It just sits with a deep black screen and doesn't even turn itself off with the remote. I am super pissed off with Samsung now.

eliasp9 (author) on January 07, 2012:

Thank you very much for all the comments.Glad i was able to help someone.

bostondann on December 26, 2010:

Thank you for this information! After 13 months of ownership (just past the warranty expiration) my LG Plasma TV developed a serious problem. These include picture degradation, shutting down at random, screen lines, color degradation and others. We systematically applied solutions such as switching cable locations, using different cables, trying a variety of power supplies (basic strips to battery backup) and nothing seemed to help. We observed the TV in different modes and kept having the same problems whether we were using the Set Top Box (cable), the DVD player or the gaming system. One observation stuck out form the rest – the problem did not occur when we were watching a black and white movie. But as soon as the film ended and we switched to a color movie, the screen popped and went blank.

I started researching the issue on-line (thank you Google!) and after some trial and error with search terms eventually discovered other plasma television owners with similar problems – some have been kind enough to post pictures and videos that allow me to see the same problems as my plasma TV. Further investigation revealed that a common culprit appears to be the Y and Z Sustain Boards. These circuit boards are akin to the vertical and horizontal deflection circuits of older televisions and are at the heart of creating a picture on the screen.

Unfortunately, the Y and Z Sustain Boards (more simply called the YSUS and the ZSUS) are a serious weak point in ALL plasma televisions. Do a Google search for problems with plasma televisions or problems with these boards and your search results will light up with hits! Information about problems with these components span years of plasma manufacturing and cover a wide variety of brand names. The worst offender seems to be LG – especially since they manufacture these boards as components for many other brands and have been doing so for many years.

Doubly unfortunate is that this problem seems to be rampant in the plasma television industry yet no one seems to know about it. It does not seem to be a safety issue (no fire hazard, etc.) so the Consumer Product Safety Commission has no information on it, it is a standard component of larger items with no particular brand involved, so the Better Business Bureau has no records on it, and the issue is spread out and technical enough that the average consumer seems to be unaware that it is such a large issue. How many plasma TV owners have to have this problem before it becomes general consumer knowledge?

In other words – this is a KNOWN ISSUE with plasma televisions yet it has somehow fallen through the cracks of consumer knowledge and the plasma manufacturing industry is certainly not be\ringing to anyone’s attention.

A call to LG customer support was less than helpful. The customer service representative on the other end of the line had no information on this issue (even though it is quite common). I knew more about the inner workings of my television than he did. The LG warranty does cover the “Panel” for a two year period – and these components would appear to be core to the “Panel” – but the service rep I spoke with could not provide me a definition of what is included as part of the “Panel”.

To put this in perspective, my family once owned a Sony Trinitron for nearly 20 years before it was replaced and our former primary television (still in service) is a nearly decade old Sharp CRT unit. Neither of these units developed the problem this LG Plasma is having and neither ever needed to sort of repairs (both dollar and labor wise) that this plasma unit needs. So yeah – this is big deal. When I spend the kind of money necessary to purchase a product such as a television, I expect to get more than 13 months of service out of it. I intend to get this unit repaired or replaced and I do not intend to be the one paying for it!
