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.

I fixed my plasma TV after watching your video, plus a new part from Ebay.
Hi Jimmy. When i plug in my TV it turn on and tick 3 time and power off. I took it apart and check inside. When i plug in the cord from main onto power board the main board flash 3 time and my dies powers off again. Is it my power board or main board. Please reply.
Good day, your overview of Plasma TV presentation was second to none. Although you had not touched on audio processing of it - I had really enjoyed it. Much appreciated.
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....
what about thin vertical pinstripes across the entire screen? shows black on a color test image. equidistant from each other?
I'm not sure but ,if anyone else needs to find out about

try Saankramer Electronic Magazine System (do a search on google ) ? Ive heard some awesome things about it and my mate got great success with it.
@@mercylopez5181 I did a google search that’s why I’m here 😂😂
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.
Can I change plasma screen panel to an LED TV
I realize this is an old post, but did you get the logic board installed and did it fix the vertical colored line?
Shopjimmy.com I have an samsung plasma tv model number PN60F5500AF. It flashes a pink or purple then the screen goes black with sound. I have to turn the tv off then back on to get the picture to come back on. Can you tell me what I could do to repair this problem?
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).
I have a LG 60pv450 that shuts off after a few seconds of running. There is a standby light but it won't power back on after it shuts its self off. The screen will light up but it goes off again right away. We did have a fuse breaker pop this summer and it's the same plug that runs the tv. Would this just be a fuse in the tv I could repair? Thanks
Jake T im having the same problem with mine. did you find a solution yet?
me too

@@emmanuelngakane6883 it's the powersuply
I also have this same issue, mine will turn on and we'll do fine as long as it's only displaying the no signal icon that dances around the screen, but if I power on a PlayStation or DVD player and the screen gets more I would say power or light in it it shuts right off
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.
I have the same exact issue with the same tv...
did you find a resolution yet?
I replaced the Y-Sustain Main board with a used one I found on eBay and that fixed my TV. You can also find someone to repair your bad board on eBay.
@@LesLariz I have a 30 inch LG Plasma EDTV from 2008. Works great, BUT I have to turn it off and on 3 - 4 times to get a picture! Sound comes right on. Who can replace a "board" not me - who do I go to?
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
Thanks for your great video. I have a Samsung plasma tv 860fh-yb06 Manufactured 2014-06-02. The problem is vertical lines have appeared on the right side of the screen. It sounded like it might be the logic board. I'm not sure how i would get feedback from you. Again thanks for your help.
When i turn my tv on it stays on 1 maybe 2 seconds and then turns back to the red dot

Ah, needed a good chuckle... laughed out loud for a while on this one
thats easy ,replace your brain,,hope that helps.
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?

Hi Jimmy, My TV has 2 thin black horizontal lines - Samsung PNC50C450B1D. My guess, I will eventually need to buy a Y-Sustain Board. Can you confirm, and indicate cost and difficulty if I want to replace it myself? Thanks, Chuck

ShopJimmy.com I have a Panasonic tc-p50s60 plasma tv. When power is hooked up the standby red light comes on steady, no blinking. No audio or video. The fuse on the power supply board is good. I'm thinking I need to order that board from you. Am I on the right track?
Hello…you guys have been able to help me with diagnosis and parts for Panasonic plasma tvs before…hopefully it’s the same here…working with model TC-P50S60 that has both horizontal and vertical lines usually after it’s been on a while….last time I had lines on one of my other units it was t-con board and buffer boards but tha was just horizontal lines if I remember correctly…any help as always is greatly appreciated
Hi, I have a Philips Plasma 50PF9731D/37 with White & Red vertical lines to the far right of the screen. The TV almost makes a loud buzzing noise when it starts up but tends to dissipate after 15 minutes. I appreciate your help with any suggestions. Thank you!
Hi, very intuitive video... I have the Samsung D550 51inch 3D plasma TV ... Recently we heard a popping noise and we lost picture. There was sound was still playing until we tried other av sources and couldn't get back.
Any idea what could be the specific problematic board?
Thank you for the video. We purchased our 42" Samsung Plasma HDTV in late 2006 and has given us flawless service since that time. I have it connected to a TrippLite HP1000 UPS for a seamless AC Source and power down. Just in the past week I have noticed that the TV has a grainy appearance during power up, and has a slow pulsating appearance with the grainy picture and it all goes away after about 1 minute after power up. No other issues. The picture is good without any lines or abnormalties. The model number is HPS 4253X/XXA S/N B15G3CNLB08739; Mfg Date Nov 2006
Our panasonic tc-55st50 is overheating after 30 minutes of use. I took off the rear panel but everything looks ok, although I don't really know what to look for. Any ideas?
Some TV's have a very small cooling fan! Check to see if it's running if yours is so equipped.
When working on a plasma TV like this, does it need to be discharged for safety like a CRT would and if so can you point me in the right direction for information
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?
Colorful snow. It doesn't fall, but just exists on the screen & seems to be getting worse, everyday. It is a 50 inch Samsung Plasma Mod# PN50C450, 720P HDTV. I purchased it in 2010. I use a Roku devise. All Roku channels I visit have the snow. I'm not connected to cable. What do you think is wrong & can It be fixed? I loved your video, very helpful in understanding the inner workings of TV's. Many Thanks, Norm
Real basic question, the three long white connectors on the left of the image. How the h... do I take them out? Thanks. I know, I know... 🧐
I'm struggling with this as well. I got them out, replaced the board, but cannot get this cable back in!
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
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. VSUS 195v, TP15v and Ve 165v all come up and shut down within a couple of seconds. Disconnecting both SU and SD boards, all VSUS 195v, 15v, and Ve 165v come up and stay up. 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!
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
I have a Samsung Ps50c7790ys plasma tv, that has since last week 2 small black horizontal lines on the top of the screen. First appears 1 black line and 2 houres later the second. Sometimes the TV resets by its own and switches on. You mentioned theses problems due to a defect y-board.
Do you think it's worth it to swap the y-board?
Have a plasma TV. Power clicks off 2 seconds after hdmi tag shows in corner. I suspect hdmi chip on mainboard is the problem. But may be just the power supply board. Power supply and mainboard only connected and clicks off on same after 20 seconds. So one or the other? What do you think.
Panasonic TC-60PS34, built 5/2011. Have been getting white screen (like looking through cheesecloth) with sound for about a month, when turning on. Turn on and off a few times and it worked fine. Now it is just white screen with sound. Open back and everything looks ok. Boards are TNPA5343,5344,5399,5400 PH0914,PA5326. Do you think replacing buffers 5343 & 5344 and board 5399 will fix?
Hi Jimmy I have a Pioneer Plasma tv PDP-508XG with blinking blue light (9 blinks). Any idea as to the problem?
I've got an LG 60PM6700-UB plasma television. I've got audio but no picture, a black screen. I Had somebody check the Y Sus main board. They said its good. I ordered an upper buffer board and installed it but still have the same problem. I'm wondering if I should also order the lower buffer board. Do you think a bad lower buffer board would cause this issue? Great content, thank you
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.
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?
I have a 2007 Zenith 52" Z503P - model # 50PC3DB-UE.

looses picture has sound eventually 7 red light flashes
Hi. Thanks a lot for this video. I have a samsung 43" plasma - PS43E450. I was trying to sort out a horizontal line reacently so I cleaned out the ribbon cable connections and was trying to troubleshoot the issue. 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
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. Do you have any recommendations, or is it about time to give it up? Thanks!
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?
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.

This is a Samsung plasma from 2011. It is currently turning on for about 3-5 minutes and then the picture turns off and the sound stays on. From your video I am guessing its the YSUS board. What do you think?
Nicely done video here’s my question . I have a Samsung plasma TV model # PN51F8500AF Serial # Z6PT3C3CBFB02637K it works fine except for one hair thin line right in the center running vertically from top to bottom. Any ideas on what might cause this?

Hello, great video. I have a Panasonic plasma TV, Model: TX-P42S11B that turns off and the standby light flashes red 8 times. When I disconnect the SS board (X Sustain board) and power up the TV I will get a picture. When I disconnect and reconnect both the SS board and Y sustain board the TV starts working fine. After a few days I will have the same issue, the TV will turn off and if I disconnect and reconnect the Y and X board the TV starts working again. TV’s working duration time has also been going down from a week to a day or two now. Any suggestions which board should I replace to fix problem? Thanks!
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.
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.
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.
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?
Hello, my Phillips 42' plasma Model 42pf7320A/37 presents a blinking red light after attempting to turn on. I removed the back panel and found two bad capacitors.
This occurred after a power outage due to a storm, after the outage the tv sometimes would turn on and sometimes I got the blinking light. Now, it will not turn on at all and I get the continuous blinking red light.
Besides these 2 capacitors, is there anything else I should replace? And how can I send over the photos to identify the caps in my tv?
Big thanks for the time!
I have a 60 inch LG plasma TV and it would turn on and then after a few minutes the screen would go dark, then it would power itself off. If you turn it back on it will work but will always turn back off. I listed it for sale and described the problem it had. A guy messaged me and told me if I could solder, I could fix it. One on of the boards, these little coils had developed cracks on the bottom of the board.. I repaired them and re soldered them and the TV started to work great again. It's been about three weeks and tonight, it started doing it again.. I took it apart, added more solder and made sure it was done better as I kinda rushed through it the first time. I plugged it back up and about 10 minutes after turning it on, it did it again.. I only did the board on the right side of you're looking at it from the back with the cover removed. I checked the other side and they aren't cracked like the right side was so I didn't mess with it.
I'm having that problem
@@abelhansen3879 last night was the first time since I did the repair that it happened. I re did the soldering and really took my time. Put it all back together, plugged it in, turn it on and about 10 minutes later kicked off.. I turned it back on and it stayed on until I woke up, 9 hours later and I turned it off. The soldering definitely makes a big difference. The people who have the videos of putting the main board in the oven, thats what they're doing, that gets the solder hot enough to seal the cracks that develop on the underside of the boards.
So I've laft the back panel off so far it's been running 40 min without turning off this and a fan blasting air up across the back might just be all I need
Hello- I have a Samsung PN64D8000FFZXA Plasma TV. The red indicator on the front of the TV lights up when turning on the TV, but no picture or sound. I have replaced the main board, but still no sound or picture. Any ideas? Thanks!
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.
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
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!
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?
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.
Hi, I have a 55” Samsung plasma tv model pn51f5500af
It will not power on. Red light comes on and flashes 2 times … continuously… no clicking, no sounds…just the red light.
I opened the back, no visible problems… one small green light comes on on the board with hdmi connections etc.. but flashes a few times.. then nothing when powered on.
Can you help? Is it a power board issue?
Thx
pn50c490b3d samsung plasma 2013 plug into wall and hear clicking took off back panel unplugged from main board and clicking stops appears to have 3.7v standby voltage. Thinking it is a bad main board. Thanks for any future input.
Hi I have a LG plasma TV model number 605500 - UA I cannot get my remote to operate the TV and then when I try to use the TV control buttons on the TV the channel does input volume does channels is all messed up what do I need to replace to fix it thank you
Hello sir, i have panasonic tx-p37x10e, it has fat verical black line, i openes it, i think ots the third flat cable on boaed at the bottom, nothing looks damaged. On the side edge of the black line there is a thin line but its static/snow.
Great video. I have a Tatung P46T Plasma. It will go into standby mode; however, when it is turned on, it begins making the loud popping noise you mentioned, and the colors on the screen are distorted with no definable picture just ghost images.
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.
I have a Samsung 858FH-YB06 tv that won’t turn on. The green light in the back of the tv flashes. I’m now subscribed.
Thats what I got that loud pop no picture 50' vizio plazma jv50p hdtv10A is it possible to still get a board for this TV?
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 ?
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 🙏🏻
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
60 inch lg plasma clicking . Trying to power up but don't. So far found a blown ceramic capacitor on y sustain board replaced but no change .the 1 large heat sink on board nearest to buffer connections . Has 3 mosfets 2 same 1 diff specs . The 2 - 1 gives unusual ohm readings . I know they act as a gate for voltage but I do see some discolouring new that particular 1 ..
Ty in advance
I have a 65" Samsung Plasma TV model PC8000 and I am not getting any signals thru the HDMI connections I have verified that the cable box is putting out a signal and the TV screen just says no signal found. What do you think the problem is?
I have a LG plasma tv model 50pa5500 and I keep getting pop ups screens telling me that there is new external input and jump from av input to component 2 one right after another..I have hard reset and also put back to factory settings per LG people and said I need repair...can you help with this.or is it time for a new TV..what good to buy?
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?
hi. not sure if you're still answering questions... but I have a LG model 60PV400-UB and my picture was getting screen burn, but then on the 4th it just turned off on us, and now won't show any picture. sound works, but no picture. It flashes in the corner and across the screen black and white for a second upon turning on, but then nothing...just black. any ideas?
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.
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.
So I have a 50PA4500 LG that clicks on when powered and stays red. Took cover off, on the little board labeled CTRL there is a green LED flashing a pattern of 3 short green and one steady green. Tried the unplug/hold pwr for 30 seconds to no avail. Can you help?
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?
I have a Samsung PN64D7000 plasma TV. It won't turn on and the red light dimly flashes twice when hitting the power on button. If I unplug it for a while and try it again it will eventually turn on and work for a while, and then it repeats the no power problem. I don't want to buy any parts until I know which board is causing this. Also, if one of the boards is causing this does the board itself need replacing or just some components?
Hello. I have a plasma Samsung PN50a400c2d manufactured in 2008. The tv wasnt used that much over the years. I have a section approximately 4 inches wide that is either solid black or colored vertical lines from top to bottom. I have replaced the logic board in center of tv and also the input board. I have had times where it will go away but once powering off and back on, it reappears. One ribbon cable on the center logic board connects to what I assume is a backlight board that goes across the bottom of tv. I have reseated and cleaned the ribbon cable ends. I currently have a ribbon cable ordered. I removed and swapped ends of the ribbon cable but lines remained and in the exact same place. I am not sure if the backlight board (I assume that is the board) can be replaced. Hoping issue with the ribbon cable but dont want to keep replacing parts without decent chance of it resolving problem. Any suggestions? Thank you!!!!
I have Samsung Plasma TV PS51F5500. It gave very loud pop sound, then screen goes blank.
Immediately turned off.
A day after that, I turned on again, the loud pop sound once again came.
After that, now once turn on, no pop sound, no display at all, front red light on, after few blink, then totally OFF.
Opened the back cover, cannot find anything suspicious (blown capacitor, switch, etc).
Is the power supply board needed replacement? Thanks in advance for your advice.
Hi, my TV is Samsung Plasma PDP51F5500 model. Recently I heard a loud popping noise and the video was off but audio was still coming. So I tried to restart it. Once I switched off TV, it doesn't turn on. The led keeps blinking continuously but doesn't turn on at all. If I plug out and plug in, then it's again in stand by mode, and if I press power on button, led keeps blinking? Thanks.
G'day, My Pioneer plasma is the last of the analogue tuners. The picture has started dropping out no matter what input is selected. It doesn't affect the audio. tapping the display or box and wiggling the leads makes no difference. I didnt see this symptom described at all in this clip. Any ideas? Thanks
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 !
I have a Panasonic TC-50S30 that won't turn on. No power led, no blinking led's. I can hear clicking when i plug it in. There is +5 V on one of the power supply pins going to the main/tuner board and there is one led on the ir out connector. that comes on for a few seconds. Checked PS for input voltage , fuses and for short ccts. I'm leaning toward replacing the P.S.
Your comments would be greatly appreciated. Doug
I have the following plasma TV: Samsung pn51d450a2d. The bottom (1/4) portion of the screen isn't working. The top (3/4) of TV works perfectly. Any idea what it could be? (problem is horizontal) My son says a plastic ball hit it.
Thanks
Hi, I have a 60 LG Plasma TV Model 60PZ550-UA. The TV turns on and I get audio but no video. Before the TV ultimately stopped showing pictures the colors started going bad. Please help me identify which board needs to be replaced. Thanks
Good day ShopJimmy, my TV is a Samsung 43 inch plasma with model number PF4900 BN63-1028A #8DC22 and it has a problem of displaying false colour, mostly in green and purple like its NTSC. I have changed the main board and yet it still happens. Please what is the component responsible for proper colour in that TV? Thanks.
I have a Samsung pn60e7000ffxza. I changed the y-sus out because it was turning off and on then one day made a loud popping noise. So unplugged the tv, and plugged it back up now it just cycles through over and over. Any suggestions on what I should replace if it’s not the y-sus.

Have a Panasonic Plasma Television, Model No TH-P50VT20A, which when you turn the power on, the red power light comes on, then when you then switch on the light turns to green as it normally should, but 5 seconds later it switches off, doesn't come on at all, prior to this the set was working perfectly, picture normal, now nothing, no picture, no sound, no nothing, can it be fixed
So as soon as plugged in my logic control board I got my clicking issue no other board I tested click prior. Do I have to also disconnect t my logic buffers below left and right of TV there ribbons or just replace the board it self ?? No pic red light is on front of TV.
I have a Samsung plasma 2009 model number LN40B530P7F that develops a flashing screen after it has been on for a while. I can unplug it for about 30 minutes and it is fine for sometimes a few hours. Sometimes I just let it flash and it will resolve itself at what seems like at the end or start of another commercial. Is it worth trying to find which board is bad?. It really has a better picture than any of my new TVs. Thanks
I have an old SumSaung Plasma model TV model 850HW-YB07(mfg 2011). It had faults recently with symptoms of no display and had power ready red-light short blinkings and goes away when turning on by the remote control. 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 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.
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?
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
