    LC-52D85UN making different software sharp boards WORK

    i promised myself if i made this work i would share it with you all and it did so here it goes.

    finding the right board number may be easy but matching your software numbers are not always available. it can be pretty frustrating so after checking out the service manual and finally locating the program IC i was able to pull the IC from the old board and place in into my new board. this is IC8453. its on the bottom side of the board under the metal casing. attached pictures as well. easiest way to remove is just some hot air take your time dont heat it too fast or too long. then clean the paths on your new board and solder/flux away. check connections with a 10x loupe and your all set.

    models included with this board number are

    LC-46E77UN
    LC-46SB57UN
    LC-52E77UN
    LC-52SB57UN
    LC-C4677UN
    LC-C5277UN
    LC-52D85UN

    The board i had was damaged due to a surge and was a DUNTKE833FM11 but the only board i could find out there was a DUNTKE833FM07. set is working great now. hope this helps someone out there.

      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.

      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

      Problem

      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

      LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
      by Hakuu
      Hi There,

      This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

      After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

      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...
