    Samsung LA32D40s HV320WXC-200_x-PCB-X0.0 blank,backlight OK..

    Hello, I have Samsung LA32D40s lcd tv with blank screen, but backlight and sound are ON. This TV have been dead before due to thunderstruck, and the repair shop replaced the lcd panel but after some time this TV malfunction again. The repair shop said that the lcd panel dead again.

    Turn out, the repair shop replace the lcd panel with another compatible panel ( glass only, not include with housing and backlight unit ). The model on tcon board says HV320WXC-200_x-PCB-X0.0

    I have tried to probe the voltage on TCon board, but I dont have any reference what normal voltage should be.

    VGN : 2.5V
    VGH : 16.5V
    VCOM : 7.5V
    V10 : 7.4V
    V9 : 8.3V
    V15 : 2.9V
    V17 : 0.3V
    VOFF : 7.9V
    VON : 24V
    DVDD : 3.3V
    AVDD 1: 16.9V

    Above are the voltage reading...

    If anyone here have any knowledge regarding this particular panel, Would you please help me troubleshoot this TV ?

    Thank you... Appreciate any help...

      SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
      by triplefour
      TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

      tcon is built into mainboard.
      Only one cable goes to panel boards.
      there is a cable from one panel board to the other that links them.
      cost cutting measure that results in us having harder time to diagnose.
      removing the link to the second panel board allows TV to stay on with stable backlight but no image.
      used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

      Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]
      by NWArkGuy
      Well, I will be the first to admit that I screwed up...

      In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

      I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

      I have 2 that I have found and have in my possession. ...

      Samsung UN50TU8000 - Dead Panel Forensic Questions
      by KYBOSH
      I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).





      When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
      When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.






      Later I checked for shorts on the panel PCB boards but could not find anything.
      When I took a look with the FLIR i noticed the 2 resistors...

      Samsung GU50TU8079U bad panel diagnosis
      by Ierwin
      Hello,

      I was given this Samsung GU50TU8079U that would power cycle after a couple seconds, sometimes a few minutes. The screen would turned cloudy dark with the backlight still lit and then the sytem would restart.
      Its one of the newer screwless Samsung models that I read a lot about panel failures here. It does not have a sperate T-CON board, just one ribon from the mainboard to the panel board and a U-shaped ribbon cable connecting the other half.
      I went through the usual diagnostics:
      unplugged the mainboard -> tv stayed on
      removed the U-Shape robbon ->...
