      Anyone know anything about why this might be happening? I have the same issue with my 42PF7320/98. It remains on for a while(random amount of time) before shutting off on its own. I have to unplug the unit for a bit and plug it back in for it to turn on again. Since the time is random and I haven't been around when it shuts off, I haven't been able to see if or how many times the red light blinks afterwards. I've read in another forum that some people fixed this issue by adding a heat sink on top of one of the chips. I'm not quite sure which chip, though, because the model in that thread had slightly different placements of boards than my model(the model discussed in that thread was the 42PF7320). Also, I already have the back open and all the capacitors seem to look fine. I know that doesn't mean they are actually fine but I don't have a meter at the moment to check each one individually. Any help would be appreciated. Please bear in mind that I'm a beginner at dealing with electricity but I can do simple tasks such as replacing capacitors.

          I just noticed that the TV doesn't actually turn off, the screen just goes blank but the green LED is still solid. When I press buttons on the remote, I know the TV is detecting the action because the green LED blinks as I press the buttons but nothing is displayed on the TV(if I press the volume up or down, the volume bar doesn't show as it normally would). Again, this is fixed by unplugging the TV for a few minutes and plugging it back in. What do you guys think the problem could be?

              My Plasma Philips 37inch chassis FTL2.1 does no picture ,and goes into protection mode after 30 seconds (red led blinks at 3Hz).


              Can someone has any symptom like this ?

              Problem is when turn on tv backlight flash only one time for about 1 second then turns off and display is dark but sound is there.
              Sometimes TV turns on and work with no problem, had backlight and picture, but mostly Tv wont turn on backlight. Any idea where to start looking?

              Gaming Laptop Zephyrus S17 TFT not detected every time !
              by titomno2
              Hi guys,
              I post my problem here because I think it could be a capacitor related issue (Asus support on this particular subject is non-existing).
              So the computer is a Zephyrus-S17-GX735LXS-26T and the strange behavior is seen.
              On cold start most of the time the internal screen is detected and a picture it works fine until shutdown, sleep or deep sleep.
              Then the screen won't work for a long period of time.
              If I wait 1 or 2 hours it work again most of the time.
              When it doesn't work the batterie indicator blink 3 times white stop and the same schematic is repeated...

              Panasonic th-42px60en plasma TV takes time to turn on and make clicking noises
              by novak2
              Hello there,

              I recently bought a Panasonic th-42px60en plasma TV second hand. The problem is :
              The TV takes time to turn on from cold (being unplugged from the night for example), it tries to turn on with the clicking sound, then shuts off, then retries and so on. The TV is still working, just it takes time to boot.

              From what I've read it seems to be bad capacitors on the power board, but I just want to see if anyone had the same problem with this TV.

              Thanks in advance.
