    Panasonic Plasma TV, TH-42PX60U, strange issue with picture

    PanasonicTV, TH-42PX60U turns on as it normally would with picture and audio displaying correctly. After 30-60 minutes of watching TV, the screen goes dark with audio/sound working.
    I don't have a voltmeter to check the voltages and that's why I thought I'd ask before if anyone knew what would could be causing it. I pulled the back cover and removed as much dust fom the boards and the vents as well. The backlight seems to be working properly because the TV turns on and a picture displays on the screen. Any suggestions would be helpful.

    I took some pictures of the back with close ups of some of the boards maybe someone might notice something.

    Thanks!

      I would certainly start by clearing all the dust from the circuit boards and especially around the fans and then see how long it stays on.
      Willing to help but I'm no expert.

          T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

          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)...

          by CyberPhoenix
          Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,...

          Panasonic plasma TX-P42ST50 - 6 blinks
          by jm1234
          Hi,
          anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
          It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
          I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
          I checked that board for any obvious faults...

          Having said that I come to the gist of my post on the forum as the title suggests.
          For my passion for technology I'm now collecting several...
