Sorry Guys, I had to edit and re-upload this Video due to a *copyright claim* from the movie I was showing on this Tv at the end of the Video. Please *re-like* and *re-comment* . Appreciate it.
I had to represent and subscribe. I just start my business last year and was starting to get discouraged because it’s not picking up yet but seeing and watching you got me even more motivated. I’m looking forward to checking out the course as well.
26:40 He plugs it in and sees 206 volts. Then there is a smooth subtle cut in the video and he goes to testing ohms and diode mode. You may not notice that during the cut he unplugged the TV, so don't try to test ohms or diode mode with the TV plugged in!!! It's hard to notice, but look at the power cord at 26:40 when he plugs it in, then look at 27:00, the power cord is not there but he doesn't mention that he unplugged it.
Good day Marc. I own a Plasma 3D Samsung 60" PS60F5500 and it worked great since February 2014 - although it did not do very many hours as this room is used mainly for XBOX games when the grand children visit on a weekend maybe twice a month. Unfortunately it has now died, and only double flash the standby light in sets of five times. I disconnected the Y-sustain power cable and the TV then powers up and makes bleep sounds when I toggle its switch up and down, but no display. The Y-Sus board part number is ZB 958B A3 391 5XH - BA3. I tested the Mosfets and found two (marked 30J127 - and below 3:K) that are shorted - Q5002 and Q5003. I removed the cap C5172 to gain access to removing them. The Cap tests ok. Apart from this there are 4 big components on the largest solder patches in a group in the center of the board close to these two mosfets, and it would seem that they might also be shorted, although I did not remove them to test - might need a hotter soldering iron for this. The two buffer boards have no visible burn or dry solder indications that I can see. I will really appreciate your help in getting this resolved, as it would be the end of my really stunning Planet Earth, Life and other nature, documentaries and more titles of my 3D collection. Sincerely appreciate all the way from Pretoria, South Afrika, Dawid Sadie (dawid.sadie@gmail.com).
I have a feeling this field is coming back strong and here to stay for a while. Just look at rate in which record players are being sold now. In the last three months, I have repaired Marrantz, Onkyo, Techniques, Pioneer, Denon, Yamaha, BSR and so many others that I can't remember. Really reminds me of the seventies when I got into the trade.
I watched the whole video even when that was not the failure of my plasma, and then right in the last seconds you gave me a good tip and starting point to repair it cause the scenario you described about having backlight but no video is exactly what my plasma does. THANK YOU from México
9:32 and 35:53 (very helpful) "Has sound, no priming and stays black" That describes the exact problem with my LG 60PK550-UD. I found 3 broken/separated "lugs" (lugs for the screws that mount the 2 boards together) on the upper buffer board and the Y-board had multiple bad solder joints. I managed to solder the lugs back onto the upper buffer board and re-soldered the bad Y-board. Re-installed both boards but, "wah-wah" no worky. (It was worth a shot). Regardless, I'm now convinced I still have a bad Y-board and/or buffer board(s) after re-watching your video. The TV would never "shut-down" completely only the picture went out. Prior to this "total blacked-out screen" the input menu would always flicker/strobe (only when changing input sources, cable to HDMI etc) It did that for the past 2 years and I had my fingers crossed ...until now. Last thing is the green indicator flashes "long, short, long, short". I've had this puppy since it was new and I'm determined to keep it going. I would also like the heat from it here in "Champaign ILL" where it's 21F degrees currently LOL
Update: 60PK550 without picture, with sound: I replaced the upper and lower Y-Buffers and YSUS and all is good again. Yay! I measured the temp on the new Y-buffers and they're 122F to 128F and the YSUS was 82F to 134F at it's hottest point (after being on 5 hours) No wonder these fail after 8 hours a day for 12 years (LOL) I still have a blinking green light on the back but now it's a different sequence Long Long Short Short (it was long short long short) I never could find any info on the blink patterns.
For a pro that may be true, but for a DIYer, who is looking at saving an older 60" TV that is worth $300, it's just baaaarely worth investing $90, plus that troubleshooting time, or, actually not really worth it. But if you can, at the expense of some time and soldering, salvage a TV worth $300 for $10 or $20 worth of caps and transistors, then it is closer to worth it.
Hey BigDog8882 I wanted to thank you for your part in me fixing my PN51D550C1CFXZA Samsung 50" after watching you trouble that big screen TV, motivated me to give it a try at fixing ours, I even gave you a shoot out on my channel as soon as I posted it but I have to say thank you for sharing knowledge with me and making it so simple and clear enough for me to replace my Y-Main Sustain Board yeah. Keep Up The Good Work!
Hi Allen, great work, quick question I have. 50 inch Pioneer Plasma PDP-505PG, recently it has started shutting down with 10 red blinks repeating, if I turn it off at the power point it will start up again after 5 to 10 minutes. Also sometimes there is black burst on the screen just before shutdown. If you could steer me in the right direction for repair that would be much appreciated. Thanks in advance Paul
Very useful.Thanks.. An important sugestion .... please use numbering for your videoes.this is useful to remember by visitors to review and return in the future .
Bout to dive into my plasma because of your great job in describing and showing the work of hands on !! I’ll check back in after the job. Mine is only doing backlight on and off several times then goes off, and repeats the same process
thank you so much, i found a plasma TV and was looking for a video on how to fix it. But it had a crack on the screen and makes a noise when i start it and i thought it might be the y sus so, thanks to you now i know that it is "done for". Thanks i am not going to waste my time on it.
I had the LG plasma tv (50PQ30) stored in the basement for years with very little usage prior to storing it. I finally dragged it up to replace the same model tv which had an annoying issue of the remote not working. When I plugged it in, there was no light by the power on button. Eventually, the red light was showing up (maybe about 20 to 30 minutes later) but it was dim. It took some time before it came up to the normal brightness level. When I tried turning on the tv, the light would go from red to blue. The blue light would just blink nonstop and it went on for quite a bit (similarly about 20 to 30 mins) before the blue light finally became solid and the tv finally powered on. Subsequently, the tv worked fine with the blue light blinking minimally before the tv finally turned on. Over the course of about 6 months, I would notice the blue light blinking gradually taking longer before the tv would finally power up. Then one day, the blue light kept blinking but this time, it would not power up. Can someone suggest what the issue might be? Thanks!
Wow really appreciate the video! I have a similar LG plasma that died in a way that seems exactly like this. I'll pull it apart and take a look out of curiosity not sure if I'll fix it either way it's nice to have such a direct example to follow.
hi nice video in my case i have a similar lg model but 50 inches it does clicking the relays you can see a white light only like backlight without image and after turn off this light i found on power supply the one from two resistors 10ohm 5 watt burned i changed without result the same problem but the new resistor is not burning can you suggest me sdomething sir ? thanks on advance
Great video!! thanks! I have a 2007 LG plasma 60pc1d, it turns on and appears to prime up but I can only just make out the picture barely ,but it is so dark with barely any color. This happens on all inputs and is from the tv and I did a factory reset just to make sure it wasn't a video/brightness thing. Do you think this would be a sustain board or logic board or would I have to go through the same test motions that you demonstrated here. thanks again!
Great videos with good explanations. I have Vizio plasma tv VP422. I got problem. It stopped working. When connecting to the power it clicks one time and then as you described in beginning of this video in the dark room I see some snow picture that last about 3 seconds , and then tv is dead , no led lights ( used to be Vizio logo white on standby and orange on power on) . Is problem relate to Y sustain board or main board? All power supply voltage is correct. I replaced the main board bought from eBay but didn't solve the problem although the is no confirmation that the part from eBay is working or bad.
Thank you for making this video. I found a Samsung Plasma TV with absolutely no scratches. When I plug it in I see a solid red standby light. Using a Samsung remote when I turn it on I hear a startup sound then the red light starts flashing then goes out. The screen is black. When I turn it off I hear a shutdown sound then the red light appears and becomes solid again. Do have any idea of what might be causing this or what I should check first.
Both VS and VA voltages are present during startup then both voltages drop. At power board TP VS drops to about 50 then to 0 and VA to about 10 then to 0. Y board TP shows 200 volts during startup but X board shows nothing at start up. I've tried disconnecting both the Y board and the X board but it makes no difference. I suspect the power board may be bad just want to know your thoughts.
@BigDog8882 - I just got done replacing a fuse and some mosfets on the Z-sus board of an LG 60PV250. Typical shorting to ground crap on the Z board. The fuse now has continuity on the multimeter, but the mosfets still seem to be shorting to ground - even though they are brand new. I have had to repair these before, by taking off the old mosfets, and soldering on new mosfets. So, I know it's fixable. I really wanna save this badbody from the junk heap. Do you repair boards?
What do you think caused all those FETs to short? I could see one going bad and causing the TV not to work, but 5 of them all shorted! I think replacing the board was a good choice instead of individual component repair in this case. Thanks for the Great video 👍
@@bigdog8882 Okay cool, lots of thanks, good to know. I went ahead with all 3 and actually found a "new" Y-Sus (no aging or screw marks...real, new old-stock) Works great! It truly looks like a new TV. Your video was the most helpful of all! I even managed to fix it while having the flu 🤒- Rob
@@bigdog8882 I have a tv that had bad backlights which I verified with a tester. I replaced the backlights but they still don’t turn on. I checked the voltage at the led plug on the power supply and when I turn the tv on it jumps up to about 90 volts and then starts dropping back down to zero over a few seconds. This happens whether the backlights are plugged in or not. What might my issue be?
Hi, looking for advice for a plasma Panasonic TC-P54S2 made a loud pop sound before it stopped working. Now it blinks a red light 6 times and does not come on, no sound and no picture.
Great tutorial. My panasonic TC-P50VT25 had originally a no power problem. I put in a power board and that fixed power problem but it developed a no picture problem a month later. The symptoms are the same as you mentioned for possible main board. Powers up -no picture but you can see the screen lit up with lights off. no sound either. I could not find exact main board anywhere but did find a TC-P50vt20 board. They are basically the same set and even share same service manual but VT 25 has a io connector for servicing that the vt20 does not. The connections from main board to the other board are the same. Unfortunately same symptoms after replacement. The board was bought off ebay but from a tv shop so I assumed it was good. Is it possible main boards are incompatible or are there other possibilities for this type of failure? Also if it is main board still is there any way to repair main boards on these since none seem to be for sale?
I got a Zenith Z50PT320 made by LG I believe, the Y board is shorted, unplugged it, the power supply stays on and all voltages are ok, what are the chances the buffer boards are bad too? I can order the shorted parts cheap enough for the Y board. The boards are too expensive, not worth it. I guess I can try. RD2003, RJP63F3 and 30F124 show shorts. Made June 2011.
Hey bud dog I got a 50 lg plasma since 2009 it just went dark the other night it has sound and it worked good before. I saw your video and it was very helpful but I checked the y board and it had the right vs and va also I checked everything on the video all looked ok what else can it be????
I have a similar problem with my TV. I am not measuring any Va or Vs at the PS board connector. When I isolate the Ymain (and therefore chain and y buffer) there's still no Va or Vs. The board produces the A5v, b5v and b15V. Relays click. I thought the board must be faulty so I got a second hand one and it's the same. Do you think both boards are faulty or does the PS board get a signal to produce Va and Vs from another board like the main board or the logic board? Many thanks Matt
Them cops always trying to keep a brother down lmao! I get it. Anyway I have a similar tv I got for free, an LG60PV400 and had a similar issue where it clicked on but no picture and you made me feel confident enough to get a sustain board and throw that mug in, thanks man a lot
have a question for you I have a plasma Zenith z60pv220 made by lg also same boards The TV has picture for maby 1 to 3 min but it also had horizontal faint black ghosting bars on cartoons you could really tell at the top and bottom you can still see picture no loss in image . Also when it's cold the image is great when warms up it messes up
I’ve got a 50” Insignia, I found a Y-main board, but I’m struggling to find a buffer board, my issue is that I turn the TV on, it runs for a while, picture and audio are perfect and then it will kick off and do that “clicking” thing, trying to turn on but failing I tested and it seemed to be the Y-board as when I unplugged it and powered it on it didn’t do the booting off thing, if I can’t find a buffer board, will it be okay to only replace the y-main?
I got a 2007 vizio plazma jv50phdtv10A . Problem started picture no sound after some time the screen will turn off wait for 20mins switch off the TV and back on screen comes on works good now if turn the TV it clicks on but makes a noise the screen goes blank the power board had 9 swollen capacitor I change all 9 same problem after watching your video I think I need to change that board powers the screen
I have a Pioneer Plasma Tv, almost 19 years old now. When I turn on the TV it has no real picture, only some noise, and stribes. After some minuts, there is a fine picture an no noise. Do you have an idea? Regatta from Dennark
Hey BigDogg8882.... I am a subscriber and wonder if you can help me with a Samsung 42" Plasma Television SP-S4243 with green dots or sparkles all over screen. This problem has plagued this TV for 5 years. The green dots are accompanied by ghost-like images on-the screen. All other functions works ok. No bulging CAPS and voltage adjustments do not correct the problem. After watching your video, I am leaning toward replacig the Y-sustain board. The set is really clean and has never had any repairs. Would you mind giving me a few pointers on this problem?
Hi BigDog8882! Novice tv repair man here. I have a LG 60 inch plasma I found it tries to power on just like this but I'm trying to figure it out without the multimeter. The logic board blinks green when plugged in the board on the bottom right is solid red. When I try to power on the TV the light on the front blinks red. I was thinking maybe the capacitors but they look fine to me. The x-board (top right) makes a digital shuddering noise like a disc in a drive when trying to power on. Any help would be greatly appreciated!
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.
Hey man I’m having exactly the sames tv I found out the EBJ60730702 has an issue because of the Rjp63f3 transistors are burned and I don’t have the exact number
I found one in the trash super heavy but the parts inside are huge so i want them. What parts can survive getting wet? I want to build a dc power supply Thats high voltage.
Thats called I think "Maldischarge". Look for any swollen caps on Y-Main. Then look for adjustments like I did and adjust each slowly while TV is on a still frame.
@@bigdog8882 I ended up dumpsterizing that plasma, buddy gave a working Samsung plasma, had it for sale for months, ended up only getting 20 bucks for it. People here in East Tx don't want plasmas, especially in summer. I'm sticking with strictly LCD.
I have a 50pt350 LG TV and the red light stays on and I try to turning on manually and nothing happened,also I lost the control. Any recommendation? Thanks
Question for you. I’m working on a LG plasma. Vs is 205 Va is 55 and looks good except when the motherboard is plugged in. Disconnected my voltages look good. Connected then volts drop slowly to down to 1 volt
Mainboard is what I meant. While plugged in it dumps my voltage. I replaced the power supply which had several bad mosfets and when I swapped it the tv worked with good voltages until mows day later. Have you ever seen a main board cause a voltage dump after swapping a power supply board?
@@bigdog8882 thanks for the reply. The problem now is tv has no picture when turned on but switches on and is Getting proper voltage with everything plugged in. It was working intermittently allowing a picture but when you turn it off and back on sometimes it won’t allow a picture to appear. I didn’t change the main board (couldn’t find one). It’s not dumping voltage anymore. Should I still try to find one and replace it or what else should I look at with voltages looking good but no picture. Remember the symptoms are intermittent.
I have an LG Plasma tv model 60PS60-UA the picture goes off, some times the image stays for a day, audio is good. I change the video board with the same problem. Any suggestions.
My then 2011 top of the range LG Plasma TV finally failed yesterday (nearly 13 years daily operation). I want to try to fix it. Here are the symptoms: about four days ago the TV just switched itself off. When I turned it on there was no screen. I tried to get it going but I could not. The red light near the switch would turn to blue and the noise of switching on was still there (and the noise of switching off). Then I switched the TV from the socket (from the plug) and waited say one hour. Then it would work but after a while switch itself off. Yesterday it worked all day and then suddenly at night it switched itself off. No effort at getting it to go back on gave results. I remember we switched it off for an hour from the socket (from the plug on the wall) and then it came back but only for 5 minutes and switched itself off. So we played some card games to pass the time last night. This morning at 7 am I went down and switched the plug and then it went on and I was watching TV as normal. Then after 5 minutes or so it cut out again and I could not bring it back. What do you think is the problem?
@@theneodj I bought a cheap LED TV from LG and put the plasma one in the garage. Maybe the author of this video would care to comment about what is the most likely problem we are both experiencing so we could open the unit, as he has done, and change something or check for the fault. It stands to reason that it is some problem with either a switch that fails or overheats or some unit that shorts. It would be good to have his advice so we can fix the units and re-use them in another bedroom or sell them. I am writing from the UK.
@DrDanielHoward @bigdog8882 The picture of the LG is too nice to end up in a dumpster...when the TV works that is. I took a look at all the boards and didn't notice anything striking. Although I'm no expert like this TV genuis on video. From watching this video I learned the name of the different boards (power supply board, y-sus board, y-buffer, z-board, main board, etc). Which, I'm thinking I might take a gamble and buy 1 replacement board and see what happens (a 1/5 chance I pick the correct replacement board lol).
I know nothing about tvs but,I have a LG 50pj350 plazma TV, and there is no picture but it has sound. I watched videos that said to put a light to the screen to see if there is any light and there isn't. It's completely black. Any ideas? Thank you!
I have a Samsung 3D PN51D550C1FXZA Plasma that has over the last 4 months has started having vertical color lines that will sometimes "meld" into the picture. Is the display going bad or is it something fixable. Hate to lose the TV as my collection of 3D movies would not be as much fun to watch. Any help would be great!Thank you!
Thanks for the videos. I have a 60 in LG plasma 60PA6550. I had no picture with sound, I replaced the YSUS board with a used one. It worked for about 5 minutes, everything was perfect! Then it randomly lost picture, and turned off...... Since then I have turned it on with different results. Sometimes itll be perfect for 20 seconds then lose picture, sometimes it will just flash at the bottom of the screen real fast right when i turn it on, and no picture...... Any ideas?
I have a HITACHI 42HDT79 plasma, screen is getting pixels like bad reception, tried different antennas, indoor and roof, signals are yellow but in the 09's, jumps to the red in the 80's-90's, not normal. No green signal like it use to. DVD pic is fine. Any ideas?
I have the same problem in this video with my own TV & same model and I have searched in amazon to get those parts but I couldn't find it ? From where I can get it ????
Great video, thanks. 29:00 touching ICs is not recommended. A malfunctioning IC can give you a burn blister instantly, that has happened to me. Some other method of checking for over heating would be better. A non-contact thermometer that is so popular in COVID times comes to mind. It's "resistance," not "restistance." 30:49.
Hey BigDog! Happy to venmo for your advice. On my samsung plasma power goes to X and then loops out to Y. The chart on the X & Y boards says both VS' should be 205v. I'm getting 106v on both at X and at Y. TV is turned on, but not primed up. Stand by light works, I see other boards with LED's flashing. Is the main power board simply not giving the full voltage to the X board? Should I spend the money and replace the main power board? Thanks! -Andy PN60E550D1F
You would have to start by unplugging the x and Y boards one at a time; making sure to plug the previous connector back in before You unplug the next board. Then check the voltages again after you unplug each board, one at a time. If Vs goes back up to 205vdc; then just replace the board that was pulling the voltage down. If nothings pulling it down; then look for Bad Capacitors on Power Supply boards or try just replacing the PS. board.🙏
@@bigdog8882 Caps looked good! Will try checking each board on Tuesday. Doing my regular job fixing television cameras tomorrow, amazing how i can handle the cameras but not the actual TV's. Thanks for your help!!!!!!
@@bigdog8882 Today I couldn't get any voltage out of it. Ordered a new power board.... $45, 30 day returns. Hopefully that does the trick! I really like the blacks on that plasma TV....
Awesome knowledge presentation. But now I can't find my wallet!! HEY!! Oh, here it is. Nah, I wish you lived here in Hawaii to fix my plasma TV. Can't take the gamble for a new board, so gonna get a cheap QLED tv. Just retired... too poor for OLED. Keep up the great work!
I have a Samsung plasma tv. The problem is the TV plays fine for a while, then the picture goes out, but the sound stays on. Also, when I first turn the TV on, the red power light blinks 5 times. Any idea what the problem might be?
Aha, this is the type of LG I have. Except mine is larger. It is a plasma TV not and LED. I use it as a monitor for a desktop computer. Couple of months ago it started turning on and off, blinking away. But it is not a full time thing. Often it works okay. I noticed the tv responds rather strangely to the remote control. Pressing the power button, instead of turning off the tv, it turns off the video while the audio is still there. Pressing the power on, brings the picture back with it turning off and on blinking. It hasn't done this before. Before the tv would just turn off when I pressed the remote control power button and pressing the power again would turn the tv on. Aside from that, it is stll working for the most part.. So I don't know... I guess I will just have to wait until it gives out... or something.
I wish this guy lived nxt door, i need his help finding the problem in my 65" LG. Same issues, screen went out. It still powers on, when i press power button it clicks and lil red light comes on. And the screen didnt go out all a once, when it first started going out on me i cld unplug it and plug it bck up and it wld work again for a few days and finally it went out for good...
But my screen stays completely black when i turn it on, no bcklight flickers. So im assuming i may have other issues. Idk much at all abt tvs or electronics i cld sure use your hlp.
Hi really good video well explained I'm thinking of having a go at repairing mine. Before I do may I ask your advice. TV comes on then goes off I switch it off at mains do that several times then it will come on and be ok (may flash now and again) Hope you have time to reply. LG50pt353k

I measured the temp on the new Y-buffers and they're 122F to 128F and the YSUS was 82F to 134F at it's hottest point (after being on 5 hours) No wonder these fail after 8 hours a day for 12 years (LOL)
I still have a blinking green light on the back but now it's a different sequence Long Long Short Short (it was long short long short) I never could find any info on the blink patterns.
Excellent fix Marc well done sometimes board swaps are the only way, changing diodes and IGBT’S is so time consuming
I don't even like think'n bout it. lol
For a pro that may be true, but for a DIYer, who is looking at saving an older 60" TV that is worth $300, it's just baaaarely worth investing $90, plus that troubleshooting time, or, actually not really worth it. But if you can, at the expense of some time and soldering, salvage a TV worth $300 for $10 or $20 worth of caps and transistors, then it is closer to worth it.
@@TheLarryBrown I do it on cost, sometimes boards aren’t available, or not cost effective
@@bigdog8882 wow solid practical professional approach, need a similar board for the 42” 42p j550
Hey BigDog8882 I wanted to thank you for your part in me fixing my PN51D550C1CFXZA Samsung 50" after watching you trouble that big screen TV, motivated me to give it a try at fixing ours, I even gave you a shoot out on my channel as soon as I posted it but I have to say thank you for sharing knowledge with me and making it so simple and clear enough for me to replace my Y-Main Sustain Board yeah. Keep Up The Good Work!
Hi Allen, great work, quick question I have. 50 inch Pioneer Plasma PDP-505PG, recently it has started shutting down with 10 red blinks repeating, if I turn it off at the power point it will start up again after 5 to 10 minutes. Also sometimes there is black burst on the screen just before shutdown. If you could steer me in the right direction for repair that would be much appreciated. Thanks in advance Paul
Hey thanks for the great video….Looking at a LG 50PT350….clicks no pic, Now I know something’s to check out…thanks again…….
Great video. Is it possible for mosfets to fail intermittently? Our plasma tv started losing picture a couple weeks ago, but then it comes back.
Not really, I would say check for bad solder connections or swollen capacitors on substain boards and/or Power supply.
Thanks mane. Great overview and test procedure. I still run plasma tvs and will do so until oled come down to a reasonable price point.
Yeah, I'm waitn on a price reduction 2. I'm still eyeballin the LG C3.
Very useful.Thanks..
An important sugestion .... please use numbering for your videoes.this is useful to remember by visitors to review and return in the future .
Bout to dive into my plasma because of your great job in describing and showing the work of hands on !! I’ll check back in after the job. Mine is only doing backlight on and off several times then goes off, and repeats the same process
thank you so much, i found a plasma TV and was looking for a video on how to fix it. But it had a crack on the screen and makes a noise when i start it and i thought it might be the y sus so, thanks to you now i know that it is "done for". Thanks i am not going to waste my time on it.
I had the LG plasma tv (50PQ30) stored in the basement for years with very little usage prior to storing it. I finally dragged it up to replace the same model tv which had an annoying issue of the remote not working. When I plugged it in, there was no light by the power on button. Eventually, the red light was showing up (maybe about 20 to 30 minutes later) but it was dim. It took some time before it came up to the normal brightness level. When I tried turning on the tv, the light would go from red to blue. The blue light would just blink nonstop and it went on for quite a bit (similarly about 20 to 30 mins) before the blue light finally became solid and the tv finally powered on. Subsequently, the tv worked fine with the blue light blinking minimally before the tv finally turned on. Over the course of about 6 months, I would notice the blue light blinking gradually taking longer before the tv would finally power up. Then one day, the blue light kept blinking but this time, it would not power up. Can someone suggest what the issue might be? Thanks!
check for bad or swollen capacitors on the PS board.
Wow really appreciate the video! I have a similar LG plasma that died in a way that seems exactly like this. I'll pull it apart and take a look out of curiosity not sure if I'll fix it either way it's nice to have such a direct example to follow.
hi nice video
in my case i have a similar lg model but 50 inches it does clicking the relays you can see a white light only like backlight without image and after turn off this light
i found on power supply the one from two resistors 10ohm 5 watt burned i changed without result the same problem but the new resistor is not burning
can you suggest me sdomething sir ?
thanks on advance
Great video!! thanks! I have a 2007 LG plasma 60pc1d, it turns on and appears to prime up but I can only just make out the picture barely ,but it is so dark with barely any color. This happens on all inputs and is from the tv and I did a factory reset just to make sure it wasn't a video/brightness thing. Do you think this would be a sustain board or logic board or would I have to go through the same test motions that you demonstrated here. thanks again!
Great videos with good explanations. I have Vizio plasma tv VP422. I got problem. It stopped working. When connecting to the power it clicks one time and then as you described in beginning of this video in the dark room I see some snow picture that last about 3 seconds , and then tv is dead , no led lights ( used to be Vizio logo white on standby and orange on power on) . Is problem relate to Y sustain board or main board? All power supply voltage is correct. I replaced the main board bought from eBay but didn't solve the problem although the is no confirmation that the part from eBay is working or bad.
Big Dog, I do love your channel. Hoping to get my Pioneer 111FD working again.

Thank you for making this video. I found a Samsung Plasma TV with absolutely no scratches. When I plug it in I see a solid red standby light. Using a Samsung remote when I turn it on I hear a startup sound then the red light starts flashing then goes out. The screen is black. When I turn it off I hear a shutdown sound then the red light appears and becomes solid again. Do have any idea of what might be causing this or what I should check first.
Substain boards and Vs voltages.
@@bigdog8882 I will check them Thank you.
Both VS and VA voltages are present during startup then both voltages drop. At power board TP VS drops to about 50 then to 0 and VA to about 10 then to 0. Y board TP shows 200 volts during startup but X board shows nothing at start up. I've tried disconnecting both the Y board and the X board but it makes no difference. I suspect the power board may be bad just want to know your thoughts.
@BigDog8882 - I just got done replacing a fuse and some mosfets on the Z-sus board of an LG 60PV250. Typical shorting to ground crap on the Z board. The fuse now has continuity on the multimeter, but the mosfets still seem to be shorting to ground - even though they are brand new. I have had to repair these before, by taking off the old mosfets, and soldering on new mosfets. So, I know it's fixable. I really wanna save this badbody from the junk heap. Do you repair boards?
What do you think caused all those FETs to short? I could see one going bad and causing the TV not to work, but 5 of them all shorted! I think replacing the board was a good choice instead of individual component repair in this case. Thanks for the Great video 👍
Sometimes when one shorts, you may read a short across the other ones next to it, or it still may actually blow it out too.
There was that solder crack. Also loose screws, but that's more the mid-later Panasonics without lockwashers (check/upgrade, even on working sets).
Is it safe to try a replacement new or used buffer board(s) if you may (or may not) have a bad YSUS BOARD?
Yes, I think Bad buffer boards can blow out the Y-main, NOT visa versa. Should be OK to try If you think Y board is OK.
@@bigdog8882 Okay cool, lots of thanks, good to know. I went ahead with all 3 and actually found a "new" Y-Sus (no aging or screw marks...real, new old-stock) Works great! It truly looks like a new TV. Your video was the most helpful of all! I even managed to fix it while having the flu 🤒- Rob
Your videos are great. I’m having an issue that I can’t find help with. Is there any way to send you a question to see if you could help?
How can I help you?
@@bigdog8882 I have a tv that had bad backlights which I verified with a tester. I replaced the backlights but they still don’t turn on. I checked the voltage at the led plug on the power supply and when I turn the tv on it jumps up to about 90 volts and then starts dropping back down to zero over a few seconds. This happens whether the backlights are plugged in or not. What might my issue be?
Hi, looking for advice for a plasma Panasonic TC-P54S2 made a loud pop sound before it stopped working. Now it blinks a red light 6 times and does not come on, no sound and no picture.
Hello keeping doing the great work, I have 42lg30 that have a image problems Please help
Hola muy buenas noches cómo están todos mis amigos muchas gracias por su información y qué Dios los bendiga hoy y para siempre 😊🙏😊
Great tutorial. My panasonic TC-P50VT25 had originally a no power problem. I put in a power board and that fixed power problem but it developed a no picture problem a month later. The symptoms are the same as you mentioned for possible main board. Powers up -no picture but you can see the screen lit up with lights off. no sound either. I could not find exact main board anywhere but did find a TC-P50vt20 board. They are basically the same set and even share same service manual but VT 25 has a io connector for servicing that the vt20 does not. The connections from main board to the other board are the same. Unfortunately same symptoms after replacement. The board was bought off ebay but from a tv shop so I assumed it was good. Is it possible main boards are incompatible or are there other possibilities for this type of failure? Also if it is main board still is there any way to repair main boards on these since none seem to be for sale?
NIce one. I have a broken LG plasma TV here that I am going to try and fix with your guide.
I dunno if its worth buying the three boards to fix that tv.. i cant find em for cheap at all anywhere..its just like buying a new tv..
Book learning and real life learning Tucker is getting the best OTJ learning there is.
I got a Zenith Z50PT320 made by LG I believe, the Y board is shorted, unplugged it, the power supply stays on and all voltages are ok, what are the chances the buffer boards are bad too? I can order the shorted parts cheap enough for the Y board. The boards are too expensive, not worth it. I guess I can try. RD2003, RJP63F3 and 30F124 show shorts. Made June 2011.
Hey bud dog I got a 50 lg plasma since 2009 it just went dark the other night it has sound and it worked good before. I saw your video and it was very helpful but I checked the y board and it had the right vs and va also I checked everything on the video all looked ok what else can it be????
Change the Y main first. Also check the fuse, could be open; so yes the Vs would be there on the 1 side of the fuse.
I have a similar problem with my TV. I am not measuring any Va or Vs at the PS board connector. When I isolate the Ymain (and therefore chain and y buffer) there's still no Va or Vs. The board produces the A5v, b5v and b15V. Relays click. I thought the board must be faulty so I got a second hand one and it's the same. Do you think both boards are faulty or does the PS board get a signal to produce Va and Vs from another board like the main board or the logic board? Many thanks Matt
Should be a connector from Main to PS labeled VS ON.
@@bigdog8882 no voltage on the 'VS on' or 'VS Con' pin from the logic board.
Really good and interesting ! And I like your "et voilà" !!!!!!!!!! Merci et bonjour depuis la France
Hi mate, can i ask you why you didn't repair the y board?
You can repair also. I just replaced it for time sake. To many TV's to work on.
Them cops always trying to keep a brother down lmao! I get it. Anyway I have a similar tv I got for free, an LG60PV400 and had a similar issue where it clicked on but no picture and you made me feel confident enough to get a sustain board and throw that mug in, thanks man a lot
Hey Dog, would you do a of Sony 46hr450 Bravia on a 8 blink code. I need to try and fix mine please.
Wouldnt have that TV on hand. lol Sorry.
have a question for you I have a plasma Zenith z60pv220 made by lg also same boards
The TV has picture for maby 1 to 3 min but it also had horizontal faint black ghosting bars on cartoons you could really tell at the top and bottom you can still see picture no loss in image .
Also when it's cold the image is great when warms up it messes up
Should the tv keep making that clicking sound when it’s fixed or is that not normal?
I’ve got a 50” Insignia, I found a Y-main board, but I’m struggling to find a buffer board, my issue is that I turn the TV on, it runs for a while, picture and audio are perfect and then it will kick off and do that “clicking” thing, trying to turn on but failing I tested and it seemed to be the Y-board as when I unplugged it and powered it on it didn’t do the booting off thing, if I can’t find a buffer board, will it be okay to only replace the y-main?
If the TV comes on, then Im sure Buffer is OK. Sounds like a PS problem.
@@bigdog8882 thanks!
Amazing ser... I have also LG plasma TV 42 has sound but no picture. How to fix it.
I got a 2007 vizio plazma jv50phdtv10A . Problem started picture no sound after some time the screen will turn off wait for 20mins switch off the TV and back on screen comes on works good now if turn the TV it clicks on but makes a noise the screen goes blank the power board had 9 swollen capacitor I change all 9 same problem after watching your video I think I need to change that board powers the screen
I have a Pioneer Plasma Tv, almost 19 years old now. When I turn on the TV it has no real picture, only some noise, and stribes. After some minuts, there is a fine picture an no noise. Do you have an idea?
Regatta from Dennark
Check for swollen capacitors on the power supply and substain boards.
Hi, what do you think the problem for this 50" LG Plasma also
Hey BigDogg8882....
I am a subscriber and wonder if you can help me with a Samsung 42" Plasma Television SP-S4243 with green dots or sparkles all over screen. This problem has plagued this TV for 5 years. The green dots are accompanied by ghost-like images on-the screen. All other functions works ok. No bulging CAPS and voltage adjustments do not correct the problem. After watching your video, I am leaning toward replacig the Y-sustain board. The set is really clean and has never had any repairs. Would you mind giving me a few pointers on this problem?
After replacing both substain boards (y & z), if problem still persists, then u have a bad PDP (Plasma Display Panel). Thanks for subscribing.
Looking good. Keep those great informative videos coming.
Hi BigDog8882! Novice tv repair man here. I have a LG 60 inch plasma I found it tries to power on just like this but I'm trying to figure it out without the multimeter. The logic board blinks green when plugged in the board on the bottom right is solid red. When I try to power on the TV the light on the front blinks red. I was thinking maybe the capacitors but they look fine to me. The x-board (top right) makes a digital shuddering noise like a disc in a drive when trying to power on. Any help would be greatly appreciated!
You need a multimeter to chech the Vs line for voltage or a short on both of the Substain boards and buffers boards.
@@bigdog8882 Yeah figured as much, appreciate it!
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.
Simply excellent!!!! My humble thanks. 👍👍

How to solve issue.
Check for loose solder connections and bad capacitors on Power Supply board.
I have a 50PCdD LG plasma, I have red sparkles on the darker part of the screen, what causes those?
Thats called I think "Maldischarge". Look for any swollen caps on Y-Main. Then look for adjustments like I did and adjust each slowly while TV is on a still frame.
@@bigdog8882 I ended up dumpsterizing that plasma, buddy gave a working Samsung plasma, had it for sale for months, ended up only getting 20 bucks for it. People here in East Tx don't want plasmas, especially in summer. I'm sticking with strictly LCD.
I have a 50pt350 LG TV and the red light stays on and I try to turning on manually and nothing happened,also I lost the control. Any recommendation? Thanks
Question for you. I’m working on a LG plasma. Vs is 205 Va is 55 and looks good except when the motherboard is plugged in. Disconnected my voltages look good. Connected then volts drop slowly to down to 1 volt
Mainboard is what I meant. While plugged in it dumps my voltage. I replaced the power supply which had several bad mosfets and when I swapped it the tv worked with good voltages until mows day later. Have you ever seen a main board cause a voltage dump after swapping a power supply board?
@@The5150tone Mainboard probably has a short. Try replacing the Main board.
@@bigdog8882 thanks for the reply. The problem now is tv has no picture when turned on but switches on and is Getting proper voltage with everything plugged in. It was working intermittently allowing a picture but when you turn it off and back on sometimes it won’t allow a picture to appear. I didn’t change the main board (couldn’t find one). It’s not dumping voltage anymore. Should I still try to find one and replace it or what else should I look at with voltages looking good but no picture. Remember the symptoms are intermittent.
My cv56Xh-U32 plasma is not showing pictures but it shows powers and produces sound. What can be the cause?
I have an LG Plasma tv model 60PS60-UA the picture goes off, some times the image stays for a day, audio is good. I change the video board with the same problem. Any suggestions.
My then 2011 top of the range LG Plasma TV finally failed yesterday (nearly 13 years daily operation). I want to try to fix it. Here are the symptoms: about four days ago the TV just switched itself off. When I turned it on there was no screen. I tried to get it going but I could not. The red light near the switch would turn to blue and the noise of switching on was still there (and the noise of switching off). Then I switched the TV from the socket (from the plug) and waited say one hour. Then it would work but after a while switch itself off. Yesterday it worked all day and then suddenly at night it switched itself off. No effort at getting it to go back on gave results. I remember we switched it off for an hour from the socket (from the plug on the wall) and then it came back but only for 5 minutes and switched itself off. So we played some card games to pass the time last night. This morning at 7 am I went down and switched the plug and then it went on and I was watching TV as normal. Then after 5 minutes or so it cut out again and I could not bring it back. What do you think is the problem?
I have this exact same problem on my LG plasma.
@@theneodj I bought a cheap LED TV from LG and put the plasma one in the garage. Maybe the author of this video would care to comment about what is the most likely problem we are both experiencing so we could open the unit, as he has done, and change something or check for the fault. It stands to reason that it is some problem with either a switch that fails or overheats or some unit that shorts. It would be good to have his advice so we can fix the units and re-use them in another bedroom or sell them. I am writing from the UK.
@DrDanielHoward @bigdog8882
The picture of the LG is too nice to end up in a dumpster...when the TV works that is. I took a look at all the boards and didn't notice anything striking. Although I'm no expert like this TV genuis on video. From watching this video I learned the name of the different boards (power supply board, y-sus board, y-buffer, z-board, main board, etc). Which, I'm thinking I might take a gamble and buy 1 replacement board and see what happens (a 1/5 chance I pick the correct replacement board lol).
I know nothing about tvs but,I have a LG 50pj350 plazma TV, and there is no picture but it has sound. I watched videos that said to put a light to the screen to see if there is any light and there isn't. It's completely black. Any ideas? Thank you!
Great teacher thanks man!
I have a Samsung 3D PN51D550C1FXZA Plasma that has over the last 4 months has started having vertical color lines that will sometimes "meld" into the picture.

Thanks for the videos. I have a 60 in LG plasma 60PA6550. I had no picture with sound, I replaced the YSUS board with a used one. It worked for about 5 minutes, everything was perfect! Then it randomly lost picture, and turned off...... Since then I have turned it on with different results. Sometimes itll be perfect for 20 seconds then lose picture, sometimes it will just flash at the bottom of the screen real fast right when i turn it on, and no picture...... Any ideas?
Awesome video and thank you sir.
Very welcome

29:00 touching ICs is not recommended. A malfunctioning IC can give you a burn blister instantly, that has happened to me. Some other method of checking for over heating would be better. A non-contact thermometer that is so popular in COVID times comes to mind.
It's "resistance," not "restistance." 30:49.
Hey BigDog! Happy to venmo for your advice. On my samsung plasma power goes to X and then loops out to Y. The chart on the X & Y boards says both VS' should be 205v. I'm getting 106v on both at X and at Y. TV is turned on, but not primed up. Stand by light works, I see other boards with LED's flashing. Is the main power board simply not giving the full voltage to the X board? Should I spend the money and replace the main power board? Thanks! -Andy PN60E550D1F
You would have to start by unplugging the x and Y boards one at a time; making sure to plug the previous connector back in before You unplug the next board. Then check the voltages again after you unplug each board, one at a time. If Vs goes back up to 205vdc; then just replace the board that was pulling the voltage down. If nothings pulling it down; then look for Bad Capacitors on Power Supply boards or try just replacing the PS. board.🙏

I have a Samsung plasma tv. The problem is the TV plays fine for a while, then the picture goes out, but the sound stays on. Also, when I first turn the TV on, the red power light blinks 5 times. Any idea what the problem might be?
How much would this repair cost
Aha, this is the type of LG I have. Except mine is larger. It is a plasma TV not and LED.
I use it as a monitor for a desktop computer. Couple of months ago it started turning on and off, blinking away. But it is not a full time thing. Often it works okay.
I noticed the tv responds rather strangely to the remote control.
Pressing the power button, instead of turning off the tv, it turns off the video while the audio is still there.
Pressing the power on, brings the picture back with it turning off and on blinking.
It hasn't done this before. Before the tv would just turn off when I pressed the remote control power button and pressing the power again would turn the tv on.
Aside from that, it is stll working for the most part.. So I don't know... I guess I will just have to wait until it gives out... or something.
Mine has no picture and no click. Its a samsung 69” plasma. Im starting to think its the power supply board, any ideas?
Is your expertise still available
How much was the main board
Could you do on the lg 42pn45000
I wish this guy lived nxt door, i need his help finding the problem in my 65" LG. Same issues, screen went out. It still powers on, when i press power button it clicks and lil red light comes on. And the screen didnt go out all a once, when it first started going out on me i cld unplug it and plug it bck up and it wld work again for a few days and finally it went out for good...
But my screen stays completely black when i turn it on, no bcklight flickers. So im assuming i may have other issues. Idk much at all abt tvs or electronics i cld sure use your hlp.
LG was a little tight with the solder on that board, I hate lead free solder.
I too remember when plasma TVs first came out, they were so expensive.
Now, I'm trying to fix one that someone threw away lol.
You're talented
Hi really good video well explained I'm thinking of having a go at repairing mine. Before I do may I ask your advice. TV comes on then goes off I switch it off at mains do that several times then it will come on and be ok (may flash now and again) Hope you have time to reply. LG50pt353k
