    Using a different model's logic board within the same series display

    I tried searching around but came up with nothing- In my example, I have a samsung syncmaster 712n and I want to replace the logic board/controller board completely. I can find a board for a 710n and one for a 711n on ebay. Would something like this be compatible? In these instances, the main difference I found between the 712 and the others is that the 712 has a "color support" of 16.7 million colors, whereas the others have 16.2.

    So I'm wondering, would something like that be possible? I know sometimes a slight model number difference can mean a vastly different product, but in this case it seems they're relatively close. Any ideas?

    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
    by Tynan Dill
    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

    Upon bringing it home and plugging it up, it showed a standby light.

    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

    The screen seems to blackout and stay black, but with a flashlight I can see the display.

    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

    Assuming...

    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...

    LG 60PK550 Logic Control Board EBR63450301
    by Yanleb
    Hi all, I just want to share the repair of my 60PK550-UA TV set.

    The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

    But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

    All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
    C57: 3.30V
    C61:...

    2007 Macbook logic board fault
    by tony359
    Good day all,

    I got a 2007 MacBook from a friend. The fan was not working so it was overheating.
    Once the fan was swapped, I installed an OS and it worked fine.

    The board had quite a few corroded spots so I removed it, touched those spots with a soldering iron, washed the board in PCB cleaning fluid (I've done that many times), rinsed it with distilled water, dried it etc.

    Unfortunately it doesn't work anymore. It does turn on, fan spins, power LED turns on. But no picture.

    If I see that right, I have missed VCORE on L7100 (page 59)....

    TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
    by howardc64
    All left and right refers to looking from rear of TV (or looking from front with TV upside down)
    • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
    • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
