    My 50PG20 Plasma TV [No Picture] But there is sound

    My 50 inch plasma LG TV brought for 3 years now and never been touched but suddenly one day my tv just suddenly had no PICTURE but there is great sound.
    Ive herd it might be the Ysus. But reason is i test the Y sus but it is sending great power. I take out the top Y Buffer and left the bottom buffer on and there is a Gray scale half picture on the bottom. but when i Put on the top Y buffer and take of the bottom buffer there is no picture, completely black.

    Any suggestions why my top buffer is on and bottom is of there is a completely no picture, and why my top buffer is of and my bottom buffer is on there is a gray half screen.

    What can be faulty. ?

    Please help people. I would appreciate it. all the best for me and you.

      Your top buffer is likely the culprit.

      Someone on here had the same problem with a "PG" series; this thread might be helpful:

          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...

          LG Plasma (PDP50R10101) No picture No sound
          by SluggerB
          This is my first Craigslist freebie fix attempt. 50 inch LG Plasma TV Previous owner said over time it was struggling to turn on, it would take 4-5 times to turn on, the one day it just did entirely. I took it home and plugged it in, I her a click, then a second later another click, and nothing. Dead as a doorknob

          So I took the back off and check voltages. The power supply appears fine, I checked the VS, VA, and 5V voltages and they all measured correct, on the power supply board and on the display boards (Y and X boards). All the fuses are fine
