    Vestel TV - backlight but no picture

    Hello,

    my TV shows no picture.
    It starts, the background lighting goes on, but there is no picture.
    I have already made a vestel core update. No change!
    Then I rewrote the two flash memories 25Q32 and 25Q64 - unsuccessful.

    Need help!

    Chassi: VES315WNDS-01
    PS: Vestel 17IPS11
    MB: Vestel 17MB82S

    Thank u

      Guessing WNDS panel then if not what does it use ? The samsung Panels in these are prone to this failure sometimes, check the ceramic caps on the panel board for short circuits if they are fine theres an Ic on the panel that needs swapping.

          Hello!

          Panel board means the board between panel and mainboard? There ist no ceramic cap.

                      do you get voltage on each side of that white fuse?

                                                  I have checked the temperature.
                                                  Unfortunately, nothing is warmer than 18° C.

                                                  The TV responds to the remote control only on / off and the presets button. Presets make the backlight brighter and darker.

                                                                                  The tv has no backlight, but it also has no image and sound. when it turns on the standby light blinks several times, and there is a very short flash of the backlight, as if it wanted to start, but it does not start. I have measured the voltage on the red wire of the backlight, as you have seen on the forum, and in standby it has 30v, and when it turns on it goes up to 100v and slowly drops...

The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                                                                  I ordered a supposedly ‘new' Tcon board this time, and                                                                                  ...

                                                                                  Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
                                                                                  The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
                                                                                  He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
                                                                                  I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
                                                                                  Anyway I still fully expect that there has been something seriously damaged...
