    LG 60PA6500 Plasma with sound but no picture

    I have a LG 60PA6500 that did only have a bad Z sus board, until I picked a replacement Z board on eBay that killed the picture. I thought it might have damaged the Y sus, so I ordered one off eBay, but the VY and VSC fluctuated with it. I put the original Y sus back in and removed both buffers and now VY is 189v and VSC is 0. Is VSC at zero correct with the missing buffers? I also completely removed the Z sus for testing. All voltages are with the Z sus removed.

    VS and VA have always been stable regardless of which X or Z board I switched.

    Looking for guidance on the next steps of what to test and hoping the eBay Z sus didn't ruin the panel.

      Re: LG 60PA6500 Plasma with sound but no picture

      I put the new Y sus from eBay back in and I got random voltages from VSC and VY. I think I check the buffers correctly and they appeared ok.

      Sound like a bad Y sus?

      Any way to check if the panel itself got fried from the bad Z sus?

          After 3 bad Y sustains from various vendors, i finally got a good Y board that fixed it. Added new buffers too to just make sure.

          Z sustain is buzzing fairly loudly now. Is that normal for these sets or something to be worried about?

              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...
