    LG Plasma PB6600 - Sound and gray screen then no picture

    Watching tv on my LG 60PB600 Plasma, left the room to come back to my tv off and going thru a reclicking cycle.

    1. Replaced the power supply board and can get the tv to turn on with sound but no picture

    2. Replaced ZSUS board still turns on with sound but no picture

    3. Purchased on ebay a replacement YSUS on ebay but it was cracked. Tried to install it anyways, big pop when I powered it off.

    4. Replaced logic board due to no green light flashing. Green light flashing with new board. And with original YSUS board, turns on with a gray screen for a second then screen goes to black. Sound is working.

    5. Purchased on ebay again a replacement YSUS but it came in a mailing envelope with numerous caps and resistors bent. Installed it and the tv will not turn on now and just goes thru a reclicking cycle. Plan to return this board

    Based on the above, can I assume it's the YSUS board? Found this service on ebay and thinking of sending them both my YSUS board and buffers for testing and repair - https://www.ebay.com/itm/REPAIR-SERV...0/110535815308

    Trying to decide if it's worth putting more money to fix or just buy a new tv.

    Thanks

      Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
      by KYBOSH
      Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
      No picture but you hear the TV static (white noise) playing loud and clear.
      The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
      But it seems they didn't get too far and just left it.

      When I first took a look I was amazed at how pristine the inside looked.
      Its as if the TV had been in a time capsule.
      Caps looked like they were just pulled off the self.
      Copper coils had no sign of corrosion on...

      Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
      by TR103
      Hi, I have a Samsung UE50TU with:
      - sound and backlight, but no picture
      - when it arrived, it had a picture for a few seconds
      - it keeps rebooting
      - without ribbon cable between the two panel boards, it does not reboot but I have no picture
      - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
      - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

      - without cable between mainboard and lcd panel and with a jumpered...

      Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
      by Mgiffune
      I have a 60 inch Samsung UN60EH6000F flatscreen TV. 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      ...

      Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
      by Ierwin
      Hello everyone,
      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...

      Samsung UN70NU6900F no picture and no sound
      by jchang
      Hi all

      I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



      Symptom:
      No picture no sound.
      When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
      No sound at all.



      What I tried:
      1. I tried unplugging the left or right ribbon...
