    Firstline FS4206PT Plasma - Picture goes shrinking when it's ben on a while

    Hi guys
    I got this Firstline Plasma TV

    I have it powered on and it's working OK here but according to the owner the picture gradually shrinks inwards when it's been running a while, leaving a black border. And it's an intermittent problem too.

    I thought I would see some very suspect capacitors when I opened it up but nothing is obvious

    I'm not particularly good with Plasma screen repairs - any suggestions what would be the likely cause of this type of fault?

      Seems like you need to measure the following voltages when the picture is normal and shrunk: Vs, Va, Vsc and Ve

          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...

          Trying to Save - LG 60PH6700 60-inch plasma HDTV - Powers ON but no picture
          by KYBOSH
          Saved this beast from the landfill this weekend.
          Manfactured July 2013 in Mexico.

          I love working on plasma TVs.
          Its been a while but I was lucky enough to find 2 this week.

          The TV powers on and stays on but no picture. Havent checked for sound yet.
          No bulging caps although the insides are pretty dusty and the boards are discolored from many years of high heat.
          Will start troubleshooting tonight.

          T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
          by Tr0ll
          Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

          The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

          Original T-con:
          Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

          First replacement T-con:

          I thought it might be t-con and ordered new t-con from china(supposedly tested)...

          SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
          by JJAAMM
          This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

          Problem
          TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

          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...
