    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.

      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.

      More Details

      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...

      Panasonic TC-P54VT25 No image. A or D board?
      by canadaboy25
      I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

      The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

      I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
