    Plasma Board Condition - help

    So I've been dealing with my panasonic plasma (2012 TC-P50GT50 woes for awhile now; gone through 4 main boards, always the same issue, ONLY the HDMI ports die, coax/component in have worked fine...see thread:

    https://www.badcaps.net/forum/showthread.php?t=51318

    So I utilized the PTS electronics board repair for my main board as mentioned in the above thread...however when I was hooking everything up I figured I'd give the other boards a look and found that the TNPA5670 board looked like this (pictures below).

    Is this board toast? It looks like its got some really bad brown flaky stuff around a bunch of the solder joints (is it solder resin?) Can I just scrape this stuff off with my fingernail - it seems to come off rather easily. Could this be the reason I've gone through 4 main boards?













    Thanks, hopefully I can get this thing running again as I loved the picture when it worked.

    I haven't checked the voltages yet on the power board, that's next before I hook up the new main board, but I wanted to check on this first in case I need to order a new board. For what its worth my father is an electrical engineer and has access to an oscilloscope and tons of other electrical testing equipment (semiconductor test engineer) if anyone can point me in the direction on how to test individual boards to see which is responsible for frying my main board constantly

    If my main board dies again I'm just gonna say screw it and get a new TV - love plasma's tho, wish they still made em.

    Nothing un usual, they do conformal coat these boards to protect the circuitry.

      Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
      by Dani_2024
      Hi and thanks in advance for any input you might provide!
      I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
      Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

      Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

      Sony xbr-65x900c main board issues?
      by jb_Bak
      Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

      Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
      Power Board Connector that goes to Main board
      CN6401
      Pin 01 NC
      Pin 02 NC
      Pin 03 "BL_ON": 0V
      Pin 04 "N/C"
      Pin 05 "STBY 3.3V": 3.5V
      Pin 06 "GND": N/C
      Pin 07 "AC_OFF"...

      (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

      ONN 100012588
      Issue: No Power, Then Rebooting After Main Board Change

      Short answer: replace main board and power board
      Technical answer: replace main board and Q306 & Q307 on power board.

      Long answer:

      TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      by m1ch43lzm
      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
      by cheeky2
      I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
      Obviously the same LVDS connector for the screen connection...
