Plasma TV Repair Tutorial - Common Symptoms & Solutions - How to Fix Plasma TVs

How to identify which board is causing the Plasma TV problem - How to Fix Plasma TVs

This video is designed to be a guide for testing and troubleshooting your TV repair. Please note that other complications may exist that aren't addressed in this guide. While we always strive to provide accurate and detailed information, we can't guarantee that it will fix your TV's issues.
We are going to take a look at the different boards on the back of the plasma TV and describe what each board is responsible for and the common problems or symptoms that can be shown by a TV and which is most likely responsible for those problems and symptoms.
So, the first part we are going to look at is the power supply which is right here. The power supply takes in and distributes power throughout the TV. This board is either directly connected to your AC power cord or is connected to the AC adapter. Some common problems that can happen with your power supply, is that you have a dead set or your TV does not turn on and you have no standby at all, then you know that you are not getting any power to the TV. You could have a situation where you do have standby, but you can't get the TV to turn on. That could also be caused from your power supply. You could have a bad power supply also if your fuse blows. This power supply has a few different fuses.
The main board which is located over here typically manages your accessory inputs and outputs and houses the TV tuner. So this is what sends the signal from your HDMI ports, your RCA connectors, your VGA input, all your different inputs go through here and are connected elsewhere to get the picture on the screen.
If the set in total resets on its own with you doing anything, it could be your main board that is causing that. If you are having issues with the video on the screen it could be a connection here or the main board is not allowing you to have the full resolution or clear image. Again if any of these inputs don't seem to be working with your TV it could be a bad connection here.
The y-sustain, which is located right here can also be called a y-sus board, a y-main board, and an SC board. So the y-sustain here, connects your PDP assembly through a buffer system most commonly known as a y-buffer or y-scan drive. Which is right here. Some common symptoms of a bad y-sustain, the TV shuts down and power cycles. That would be your TV turns off, and then turns back on again and then turns back off and such. So its running through a power cycle. If you have no picture on the screen, this could also be the y-sustain or if you have a dark picture on the screen. If you have a flashing screen with shadowy sections, this could be the y-sustain. If your TV makes a popping noise, which is usually quite loud and then you have no picture on the screen, this could be caused from the y-sustain.
So, the y-buffer can also be known as a y-scan drive. This y-buffer again is what connects the y-sustain to the panel. These orange colored connections right here are built into the actual TV panel and are what connect to the y-buffer. So if you have a problem with any of these ribbon cables here, they will not be repairable as they are connected right into the panel.
A common symptom of a bad y-buffer board is if you have black horizontal lines running across your entire screen. They would run from one side to the other.
Over here we have the x-sustain board. Common terms for the x-sustain board is x-sus, x-main, z-sus, z-sustain and SS board. Common symptoms that your TV is showing that could be the z-sustain is you will typically have a picture of some kind on the screen, but it tends to look very red or purpley, the picture could be very dark and flash a little bit, you could be getting slow-motion effects on the TV as the panel isn't charging and discharging pixels correctly. So that can be some common problems that could be your x-sustain.
Next we are going to take a look at the logic board. This board can also be referred to as the main logic control board, the control board and the logic main. The logic board is connected to the main board and address buffers, via flat-ribbon cables and can sometimes be hidden underneath the main board.

Great tutorial, My 60 inch Samsung Plasma started putting a thin bright green vertical line down the screen about 8 inches from the right side edge. I was bummed out and was looking for a new LED TV, I got used to the great blacks that Plasma TV's have and really didn't want to spend around $2500 for a OLED TV that have great blacks. Found your posting and you described the symptom my plasma is having so I am taking a chance and ordering a Main Logic control board off of ebay, was only $15 so no big deal if it doesn't fix it.Thank you for the very informative post.

I have a Samsung PN60E530A3FXZA plasma TV that wont turn on. Several months ago it developed a problem where I would need to turn it on, see nothing on the screen, hen turn it off and back on it it would then work. Once it came on it was fine. Now I can not get it to come on at all. Maybe you can suggest which board might be bad. I have the back off and do not see any obvious issue such as bad or leaking capacitors.The RED LED on the front blinks and then goes out so I am getting power.

[@RasheedKhan-he6xx]

I really appreciated that you haven't taken older videos down. I have a, Samsung 5 Series plasma. Been going strong 12 years. A couple of months ago I got the occasional popping sound but everything was fine on screen. Recently i get kind of messy looking flashes or overlays on the right side (looking at the TV) which were just flashes to start with but are getting more frequent and staying longer. Its like a whitish cloud or puddle tinged red, very grainy and with evenly spaced dark horizontal lines. So according to this video I have both boards gone? X AND Y? Because in another of your videos you ascribed all those symptoms to the Y board alone (unless I misunderstood).

[@edwardpictroski157]

In addition to the previous post re: PN51F8500, there are no burn areas or swollen capacitors on the power board or other boards.

[@DS-bi3fz]

Thank you for this - here is how I successfully used this knowledge to fix my Philips (Samsung boards) TV. From the description of faults, I suspected the X and/or Y sustain boards. There was a picture, but it had an out of range color stripe and was grainy. Fault happened while watching and there was a burning smell. TV continued to work somewhat. When I looked at the X and Y sustain boards, I could see some bulged capacitors - they were all 82uF at somewhere around 312-350 volts. Between the boards, there were about 18 of them. There were a couple of other bulged capacitors. I removed them and measured ESR ( a good way to tell if a capacitor is bad). Turns out on these Samsung boards, those 82uF capacitors have almost ALL failed; only 2 of 18 showed ESR anywhere near acceptable. Now, if I were to just replace the boards, I'd be getting boards just as old with capacitors just as old. Ordering new caps from DigiKey cost about $60, and I replaced all of the 18 82uF, plus about 6 others, 4 of which were not even bad. TV is perfect now. Summary: many of the capacitors in your sets are probably at end of life, and if you look closely, you will see visual signs of this (bulging at the top). You may find, as I did, that a ton of your caps were bad, and replacement is inexpensive, and a much better option than buying old boards with the same, old caps....

[@solowandslow1]

Thanks Jimmy for actually inviting us to ask you Q's! This video is great, and after watching it I believe I may know which board I need to replace, but wisdom says I should lay it out before you as well, for your input. My tv is a Panasonic Viera 65" Model # TC-P65GT50 (manuf in May 2012) the problems started after a freakingly powerful rainstorm blew up suddenly here in the midwest. the living room window was open and the side of the tv that has the main board was approx 12" from the open window, and the back of the tv got doused breifly with rain blowing in the window. Symptoms mainly affect what is happening on screen. we can be watching Cable or our Amazon FireTV stick, and suddenly out of the blue, the TV MENU graphics will pop up (as if I had pressed the MENU button on the remote), or the INPUT graphics will pop up on the screen (as if I had pressed the INPUT button on the remote), or the MANUAL CONTROLS graphics will pop up on screen (as if I had pressed on of the manual control buttons [PWR, VOL +/-, CHANNEL +/-] located on the lower right side of the unit. When these events happen, I often lose control of the unit with the remote, but sometimes the remote will still work (although rarely). When the INPUT graphics appear, it looks like a toddler has gotten hold of the remote because different inputs appear to be selected in rapid succession. Sometimes the remote is not able to control the TV, and sometimes I can 'fight throught it' with the remote and go back to the input that I want to watch. When the remote goes dead, I have to get up and physically turn off the unit with the manual power button. We can for for a long time (guessing 45 mins?) without a problem, or it can happen multiple times in a single minute. This has be going on for maybe 3 weeks. When it first started, sometimes the volume on the unit would just start increasing by itself, reaching mas vol in say 5 seconds or so. this does not happen anymore. So, what do you think? Do you think the rain fried some component on the main board? -Chris B in central Ohio

[@moninino6215]

Do you have a video showing the capacitor replacement? Or should I just look visually for the damaged capacitor and then replace it? It will be located on the power board correct?

Hello, great tutorial video! I have a Panasonic TH 42PX60U Plasma that has 7 blinks of the power light and no image on the screen.

Individually disconnecting SU and SD boards to isolate one or the other results in same symptom...no image and 7 blinking lights, yet disconnecting both allow voltages to come up and stay. What would you suggest to do next? This is a 2006 model, and has been trouble free from day one. Thanks for any assistance!

Foolish of me but I disconnected the ribbon cable from the logic board to yhe y-sustain and switched on the tv. I heard a clicking sound and now the tv does not power on. The red light flashes every few seconds and there's a small sound from the power supply board. I would highly appreciate some advice. Thanks

Thank you for making this video. I have a Samsung Plasma TV Model PN51E450A1F from 2012. When I plug in the TV I get a solid red standby light. When I use the remote to turn it on I get a startup sound then the red light starts flashing then goes out. The screen is black. When I use the remote to turn it off I get a shutdown sound then the red standby light appears solid again. Do you have any idea what is causing this or where I should start?

[@ErnestPecounis]

I own a Panasonic Viera 50" Plasma (TH-50PX50U) and years ago a black box (approximately 12Hx11W) appeared at the upper right corner. Did some resetting to the factory settings, but it didn't help. I suspect that a power surge caused this problem, but we kept the TV because the picture is simply amazing and we could live with that box. Could it be the closed captions area? I don't know much about electronics, but I am willing to at least try, if replacing a board is what needs to be done, even if at the end we'll get a new TV. Thank you, in advance.

[@audunjemtland8287]

Question: Panasonic TH-50PZ80E It's not turning on. After blinking green, it goes to a blinking red light.It still 'clicks' nicely as it's always been doing, so it seems very healthy, and there's never been any issue with the image. It just doesn't turn on. For a while, it helped to hold a remote button pressed to help it 'wake'. But it worked less and less. As if it gradually struggled to be turned on. Any ideas on this is greatly appreciated. (A local tv rep. guy diagnosed it as being 'something' with the main board.) But he didn't say what. I think he wasn't able to diagnose it as it is many small components.

[@ronmcdade2865]

Panasonic mc106hu1400 I have a almost black screen where everything that does come up is purplish and anything that moves leaves behind a slow motion effect like the pixels are taking a long time to buffer the image while the display has already moves to the next frame. Kind of like a pixel bleeding. Thought maybe z sustain? Like you might have mentioned. I know video is old but still relevant. Hoping you might see this comment and be able to help. Thanks

Hi I have a Hitachi 40" inch plasma TV model 42hds52a approx 15 years old. Over the past several months, when tuning on the main power button at the bottom of the TV, the red light would come on, but it didn't transition to green. Sometimes pressing the power button again would make it work and more recently I have to unplug for a while, depress the power button and plug back in to make it work. Now the green light will not come on, but the red still will. I know it's an ancient TV that was more than a house but the picture is great.

I know this is an old post but I have a pn59d8000 3d plasma. (long story short) I tore my acl lcl and mcl which made me rather unstable my crutch caught a chair and i crashed into a steal rack in my kitchen and it and myself fell into the tv causing the tv to fall off the stand and I got about a softball size webbing crack with what looks a slight puncture or pin sized chip of outer layer. It wasn't plugged in at the time but when I did plugged it in and try to turn it on I get nothing. Probably just have to junk it but if you have any ideas that would be great. I'm guessing it would be just as cheap to buy new then replace as it was a 2011-2012 model

At the point of failing, i heard a loud "POP" sound and then no display straightaway. I bought a power supply board from China to replace the old one in considering highly as the power supply board failure. Hwoever, having replaced, the same problems remain unchanged. I wasted my money buying the power supply(it called substitute part from supplier) as original pwer supply module is no longer available. Now i would like to get suggestions from Jimmy what the likely part goes wrong.

I got a 75 in philips tv, 75PFL5604/F7 A. We had a few power outage no longer than few minutes, but consecutive. The screen is black but if I get close to the screen I can see changing colors. If you don't mind, point me the right way 🙏🏻

[@Couch_engineer]

Hi. Really informative channel. Glad I found it and subscribed. I have a Samsung 50” plasma about 15 years old. Recently the screen has started to periodically go black but I can still hear sound. If I unplug it for several minutes, the picture comes back one. It does this every few days. The tv doesn’t have to be on for a long time for this to happen. I noticed it is also a little warmer that it used to be when I walk by it. The model number is HPT5034YX/XXA. Thank you very much in advance

[@dargelosnezumi1283]

I have the a similar problem, the tv boots with no image 9 out of 10 times but Shem it boots with images it just works perfectly until you shot it down .. really weird and difficult to diagnose

[@sunnyofficial9739]

Thanks for your passion to help us plasma TVs lovers ( have Panasonic 65 plasma works perfect for 10 minutes looses picture has sound eventually 7 red light flashes

[@alanjolin3845]

Hey Jimmy, I have a 2006 Panasonic plasma that I love, model # TH-58PX60U . having problems turning on where it goes off and the red led power light flashes in sequences of 7. Sometimes after being on a while it shuts down and red light flashes in 7s. Today, no troubles. What I'd like to know is, what does that mean and could it be cheaper/ better just to buy a new tv as I'm guessing I may be throwing good $ on a 16 yr old Plasma that gets beautiful picture and had been in storage for some time. Appreciate your insight and hope to here from you !

Hi Jimmy excellent video! I have a zenith 50" model 50PC3DB. I believe the problem is with the x-sustain board because I get thick vertical black lines, after warming up the problem goes away. What do I do?

[@gatepro1000]

I have an Emerson ,manufactured by samsung model #S42AX-YB08. The best way to describe what the problem is the shadows on the whole screen appear like negative and some snow also on whole screen. The menu looks normal .If you can help I would gladly buy whats needed the repair it. Thank You.

[@JaymesRNelson]

I have a Samsung PN51F4500 AF, after an hour or so, shuts down into standby but won't power on again until power cord is removed and power recycled. Then fires back up fine for another time period. Picture looks good from a distance, but if a few inches away, looks a little fuzzy. Need to figure out which board to replace. Thanks.

[@wandaduncan8963]

Can you help with the problem that I have? My Samsung pn58b650s1fxza is cycling off and on with a black screen repeatedly. I have tried simple fixes already, which did not work. I removed the back of the TV and all the capacitors look good. None of the capacitors are bulging or leaking. After listening to the video, it seems my issue might be the Y sustain board. Please recommend

[@dneie11]

I know this is an older post but you seem to know what you are doing and your methed of explanation is very clear. I have a PN51D550C with the following sypmtoms------ Runs 3 Power cycles with relay clicking when plugged in. Will not power on when power button pressed so no picture and no stand-by led. X-SUS replaced for it blew output transistors yet, it did not correct the problem. When Either X or Y boards are disconnected the power cycle stops. What is strange is the power cycle stops when either one of the X, Y boards are disconnected. With both connected, cycling continues for 3 attempts and then tv goes quiet. PS Stops cycling with both disconnected or just one of them connected and does not matter which one is connected just as long as both are not connected. Hard to diagnose a prob with the x or y boards when neither one individually connected causes the power cycle. All voltage output from the PS match and hold what is printed on the board next to each connector. There are no bulged or oozing caps, no burned or discolored areas on any of the boards and no popped fuses on the PS. The logic board "heart beat" LED has a slow and long blink pattern when XSUS and YSUS boards are disconnected and TV when both are re-connected. There is no longer a stand-by led with any pattern of connected boards and the power LED blinks 3 times rapidly when power is pushed with no power on or clicks.(heat sensing buttons not hard buttons on this model) I love this tv and hope to fix it. I do have some knowledge of circuitry but lack the indepth knowledge of how each of the individual components communicate with one another.

[@jason300c1]

Th8s was already extremely helpful. Mine is definitely a power supply issue. Need to get the number and come back to this video.. It made a loud noise and some smoke.. then it wont tune on or be on standby

[@jamesperreault6800]

LG 60PV450-UA. I'm having issues with image quality in the top right quadrant. It has a solarization effect causing the colors to be off. It only seems to affect that section. I've seen other videos were they talk about a T-CON board, but I can't find anything that looks like that.

[@TheSwatxmr]

Sound but solid black screen suddenly happened. Thought it over heated, but that wasn’t the case. It’s a 2008 lg plasma tv 50PG20. Any suggestions and do you also sale parts?

[@sunnylife3847]

hi there, i have a problem with a pioneer plasma tv, it makes a whining/hissing noise (from the cabinet, not through speakers) that increases with picture clarity. With dark screens you hardly hear it, with white screens it is loud. It also increases gradually with operation length. After watching a movie it is over all louder. The sound resembles the sound you would have from old crt tv's. It has a high voltage static noise to it. Thanks and hope to hear from you soon.

[@davidrebidoux9722]

Hello, you mentioned that you might be able to help with an issue. I have a 2008 AVP504 Sanyo 50 inch. Way back the top of the video became dark but we could see the bottom half of the picture. Well of course not long after the bottom half did the same and away it went into storage. Been sat there, inside, warm comfortable, and ir is now that I have time and inclination to fix this bad boy. Any suggestions as to the cause and how to proceed? Thanks so much!

[@KC-me7nv]

I have a pioneer 42 inch plasma model PDP-R04U, and it has a faint screen, you can see picture, it does have faint colors and you can see it changing , but in no way can you watch a show. It also has sound, occasionally it powers off and the red stand by light blinks on the TV. This has a remote receiver connected by special system cable to the TV monitor? Any ideas on repair? At one point I did see a repair kit for the receiver and see some on eBay, would those resolve the issue?

[@XxihatenewsprintxX]

Samsung PN59D8000FFXZA TV turns on but no picture or screen lighting. On the back of the tv while plugged in I can see a small green led light on one of the board slow/long blinking above it on the board it says LED2000 LED2001. They are printed almost on top of each other any help would be greatly appreciated

[@Bodiddy]

I have a 50 inch Panasonic plasma TV model TC-P50 U2. It won’t come on. When you turn it on there is a click sound and the red “on” light comes on but the screen stays black and the red “on” light goes into standby mode (flashing on and off). Can you help? I see where the power board is, but I don’t know what the fuses look like that you refer to in the video.

[@tracyturner1359]

The tutorial was great I have a Samsung 43" plasma tv model PN43D490A1D I have picture for maybe 30 minutes then I lose my picture it has sound with a dark blue screen witch circuit board could be causing this problem T. Turner

[@KarastanCSaunders]

Great video! I have a question... I have a Zenith Plasma TV (Z42PT320-UC) where the sound stopped working out of anywhere. I'll turn the volume up, switch HD I outputs and even use the AV cords, but no sound comes out at all. What would you recommend?

[@mach.6388]

I have a LG 60PN6550.... It started out by shutting off the video but not the sound. You could turn it off and then on again and it would then work for... This happened for a couple of days before it shut off completely and when you try to turn it on now you can hear the normal click sound and the standby light goes off but then after about 20 seconds it goes back to standby. Any clue which area I should look at first? I'm guessing form the video it is the power board, is that correct?

[@robinowen3899]

Hi my house got hit by lightning. I could feel or hear it going through the electrical cables. Now my tv not working. It comes on for a while and then it switch it self off. Would it be the power board? Also HDMI does not work so this could be both main boards and power board right? Tv is a plasma PS50c680 I will open the tv tomorrow to look for any burn marks.

[@leesands9048]

I have a Panasonic thpx50u plasma and the bottom half of the horizontal picture cuts in and out from working to just black or from working to looking like a bad bulb is projecting the bottom portion of the picture. Any thoughts and thank for the videos there great. Lee

[@somantakghosh1065]

Hi Jimmy, my Samsung plasma TV PA43H4900 suddenly stopped working and my MCB tripped. Whenever I tried to power on the TV MCB trips. I checked the power socket on wall and found okay. Later I asked an electrician about this. He's saying it may the TV's PSU got short. I just want to be sure from you what may be the problem and what components are to be repaired or replaced. No lightning was struck when my TV stopped.

[@user-eg6hs1cn5f]

Hi, I have a Samsung PS51D6900 Plasma TV. It stopped working when I plugged it in and heard a series of loud popping noises. From then on, when I plug the TV on, the standby light flashes 6 times but there is no picture. I'm guessing that the TV has power and is turned on because when I touch the control panel on the TV (volume up/down, etc) the red light flashes. What board/component is defective? Many thanks.

[@JasonSmith-qx3zh]

I have a Zenith Z50PJ240 plasma TV. You can here it click twice with a red light on the front. I unplugged all boards. Then gave power to the power board and nothing happened gave power to the power board and the main board and the light on the front came on with a click. What would be yur next move power board replacement or main board?

[@woodygoodly7690]

I have a Samsung PN51D450A2DXZA N102 which powers on with a 5-6 second steady light on the logic board before it cycles off and repeats. I've tried the process of elimination of the y sustain and x sustain boards but can't get the TV to power on with an image displaying on the screen or the noticeable samsung "chime". Capacitors look good but I haven't put a meter to them yet. Any idea what I can maybe look at next?

[@bigj1able]

I have lg 50pq30r and having some issue with the screen. it will be fine for a little bit but then for 30 minutes of watching tv. then it will becomes hazy then a black spot will appear on left side on the screen.

[@abelhansen3879]

I have a lg plasma60 inch and it seems to me that it is overheating. It turns on fine looks great but shuts off after 10 min then turns back on about 2 min and repeats this. I looked into it and thought if I replaced the main power board it would be fine but I have the same problem still. Cleaning the dust didn't help jigaling the power wire doesn't help. I think it's overheating problem. Is the next step replacing another board like the parts that runs the HDMI cable

[@adaminpeds]

I have a Panasonic Viera plasma tv. Model TH-42PX60U. Manufactured November 2006. I am experiencing approx 1 inch verical black bar on picture image from top to bottom. As per your video at 5:28 in, that may be my problem. Could you please advise and where I could find that part. Thank you!!

I have Samsung plasma TV model PN58B540S3F. While we are watching it it turns itself off. We disconnected everything but the power still runs off itself. Any ideas? Tha ks

Hi, thank you for the video. I have a VIZIO VP50 HDTV 10A that has been working fine until a couple of weeks ago. I was switching between Inputs and the screen went black; the unit continues to power up but now there isn’t a sound or picture. Can you advise me of troubleshooting for this problem?

[@tonya2536]

I have a 2007 Plasma TV (54 Series) that suddenly started power cycling with a slight popping every 3-10 minutes. Assume from video that means may be a Y SUS issue but not sure how to further troubleshoot or what and where to get parts.

[@aaroncrout4876]

Hello. I have a 2010 LG 60PS60 UA 60" plasma tv. Was watching it yesterday then all the sudden no picture black screen but still had sound. Powered down and unplugged from wall to let things reset. Powered back on Powered up like it should had pic and sound was working perfect. Then 2 mins later screen went black still had sound. It will continue to do this every time now. What's your thoughts? Y sustain board? Thanks for your time.

[@lancewilkie4670]

So I'm not sure my model number but I have a 42" 720p Samsung plasma. I have a lot of pixels going out. Now I have a thin vertical line on the left side. Any thoughts?

[@VideoAmazed]

The video was very informative, but it doesn't address the particular symptoms that we are experiencing with our Samsung 42" HPS 4253X/XAA. This Plasma TV has been installed on a TrippLite HT-1000UPS to eliminate power brown outs and surges and has given us very reliable service. The symptoms ONLY appear at start up in the morning. The entire screen is dimmed but the channel chosen is still visible but is grainy and the entire screen slightly pulsates for about 5 minutes and then the screen cleans up and then appears normal. I presume it to be a power supply related issue ? Possibly an electrolytic weakened with use ? The TV works great otherwise and I hate to discard it without trying a simple fix. Your feedback would be greatly appreciated. I'm a Ham Radio Operator since 1966 and have experience with soldering and circuit repair, but not much experience with flat screen repair ?

[@asergi0rosa]

Hello - HP Plasma TV Model PL4260 - I mostly had horizontal Black lines across the screen then I started to also have light purple snow across the whole screen. Can you please let me know which board do you think it might be causing the issues. Thank you.

[@sanviarora9616]

Nice one. I have a pn60f5300af Samsung plasma. Grains are appearing on the left top side while watching TV. They are not of fix color but changes as per picture. Any idea what may be wrong?

[@raypourier2313]

Hi I have a LG 60PV400 plasma and when u turn it the TV will turn on with no picture and after couple seconds click and turn off. I took the back cover off the TV and the Y sus board makes a buzzing noise. Do u think it's that whats wrong. And I actually can't find one for it if I buy a kit does it come with everything in it to change out everything that needs to be changed. Thank u hope to here back from you

[@teddavis5081]

Hello shop jimmy you guys are awesome. I have a pn60F8500 Samsung plasma tv they say this TV is still worth repairing and that’s just what I’m trying to do. After reviewing videos for weeks on end I have come to the conclusion because my television has no standby light and no power to it whatsoever that it is my power board. Because of this I ordered a new power board I have installed it and the TV is still not powering on help. I have also tried to test the cable going to the main board but I think that is past my area of expertise

[@ashokjena]

Hi. My LG plasma TV 42PQ10R-TA having similar problem. After power on, there is a tik-tok sound 2 time then TV remain in stand-by mode. There is no picture indeed. As per my diagnosis so far...With YSUS connected, no regular voltage coming to YSUS board. If remove YSUS, voltage shows normal. I remove YSUS & check all MOSFET & capacitors. All looks good. Unless I am not checking it right. Where else should I go next ?

[@Felipe-gb7yw]

My Samsung 42" Plasma TV Model: S42SD-YB05 volume doesn't work. Everytime I tried to move it up it comes down by itself. Volumen will not stay steady at the pre-set volumen. Is this problem on the bottom board? Having hard time searching for the same exact part. What do you recommend? Note: This problem stared after plugging a fire TV stick. I reset the TV but still having the same issue with the volume decreasing by itself. Thanks in advance for any help you can provide me.

Hello, bottom 2/3 of my Panasonic tv (model TH-50PX80U) screen is black. Top 1/3 of the screen is working. Curious to know if this is an easy fix. Thanks in advance for any help!

[@jamesholmes7383]

I have a Panasonic TH-42PX60U television. The sound and picture will work fine for about a week. Then without warning, the sound will go off. The sound may stay off for random periods. A few hours, days, and once a week. The sound will without warning return; if you leave the TV on. The picture is great. There are no blink codes flashing. This is the only problem I have had with this TV since it was bought new in 2006. I replaced the PA board and that was not the problem. I now feel like it is the H-board. what do you think it is?

[@paulk7365]

LG 60Pn6500 intermittently shuts down then comes back on. Worse in warm weather. Fan on back helps but not complete solution. Took the back off today - no dust and no swollen caps or other obvious problems. Cut a hole in the back directly over heat sinks on the v-Sus board and installed a computer fan blowing in. The problem got more frequent. Shut that fan off and turned the large fan back on. Ran longer, but still shut down after approx 10 minutes. Stays off 3-5 minutes. Any suggestions?

I have a Panasonic Plasma model TC-P50C2. The tv has no picture and has a blinking red power light---blinks 10 times. Other things I have read say it is the main A board that needs replaced. Is this correct?
