    Another Polaroid TDA-03211C - main board

    I picked up one of these much written about Polaroids. TDA-03211C from 2007 with built in DVD. It had the blue / red indicator problem which I solved by replacing the caps on the power supply. Now, it powers up and works BUT after a time (a few minutes or up to 30 minutes) it begins to exhibit some erratic symptoms like pixelating, flashing screen, DVD cycles, buttons don't work. It seems like a power stability issue. I am focusing on the main board because of what I also discovered when I was fixing the PS caps. Board is P/N 200-107-GT321XA-AH rev A GT3213C-XA2. White tag on bottom of board is 21 899-KE0-GT3212XAZH Rev:01.

    As shown in the attached pictures, the coil at the corner of the board is broken. Not sure if it blew apart or was a defect but I know it isn't a good thing. Problem is, I cannot find a schematic on this set anywhere so I don't know the rating on the coil to even know what to replace it with. If anyone has a schematic or knows of a way to figure out what I need to get please let me know. My other option, though I hoped to avoid it, is to purchase an entire board off of ebay or SJ.

    Thoughts?

    Re: Another Polaroid TDA-03211C - main board

    Ended up buying the entire control box which includes power supply and mainboard. Popped it in today and works like a charm. Easier and quicker than repairing the mainboard issue but I still wish I knew what the problem was and whether that broken inductor coil was the issue. But I now have a working power supply with all new caps that I can sell.

      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...
