    insignia plasma INP4219

    Hello everyone. This tv has an intermittent problem, when you first power on everything is perfect, after 1-5 minutes picture disappears but sound stays.
    If left on, picture may come back after a couple of hours or not. before picture disappears i see black streaks across the screen. On all external inputs picture is normal and never disappears. I tried heating and cooling all modules,no noticeable effects. All voltages from power supply are dead on.....have no idea where to go from here, Hope someone can help. 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...

      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...

      Insignia Ns-l22x-10a no picture only sound
      by jose6326
      When i power on the tv a "please wait" image appears then goes away then nothing after that only sound

      When i was removing the back cover i heard a rattle.

      Removed the metal plate and the heat sink was off (see pic)
      would this cause a no picture/image issue?

      What is used to put back the heat sink
