    Vizeo P552UI-B2 led TV main board problems.

    Hi,
    I'm new to the board but like fixing electronics as a hobby.

    I got ahold of a Vizeo P552UI-B2 that the motherboard is bad. I know that because I put an eBay one in it and the TV works.

    This is a UHD TV so I'm trying to figure out what went bad on the board. The 12v and 5v on the power supply is on, I have 3.32 on the led_on terminal.

    When I plug the unit in the power light flashes and then stays on while the unit initializes but after that when I press the power button it does not boot up.

    I found one fuse on the main board but it's good.

    Anyone game to help?

    Thanks, Jeff

    I can get pictures of the other boards if needed and the backlight isn't like normal that you can unplug the main board and the backlight comes on.

      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...

      Driving a Sharp TCON/panel with a universal main board
      by advant
      This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

      I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...
