    ps42b450 Samsung plasma faulty (picture issues)

    Hi all. this is my first post. I have the plasma as mentioned in the title. it has picture problems that dissapear when i apply some pressure on the ysus board. i would hazard a guess at it being a loose connection. i have tried re-soldering all the joint.


    has anybody had similar issues and resolved?

      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.

      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...

      Sony trinitron Wega KV-HR36 picture issues
      by homerging
      Hello,
      could anyone please tell me what is likely to be causing the CRT picture quality issues as shown in the attachments and what it'd take to fix it if that is possible?

      The picture has a greenish tinge, colour scan lines are separated and there can be shimmering and the bottom can be missing at first. It has slowly gotten worse over time.

      It is worst when first turned on and slowly improves but not resolves over a period of approximately 90 minutes. Warmer room temperatures possibly have a positive influence....

      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...
