    Philips 42PF7520D/10 won't turn off, Panel glowing

    Hey guys,

    I have a question to my Philips Plasma TV. I repaired the psu by changing the smd caps on it.

    Now the tv is starting, but when I turn if off with the remote the panel is still glowing for a time for about 20-30s. Then a relay clicks and the panel is completely dark, but the stand-by led also disappear.
    If I turn it off via the button on the tv itself the relay clicks immediately and the TV shuts off completely, also the stand-by led.

    I don't what I could do. A reset in the service menu was already performed.

    Regards

      Does this TV have a digital TV feature, and are you using it?

          I just tested it with nothing connected to it. But yes this Tv set has digital feature.

              Can you use the digital TV function?
              The reason I ask is I've had several TVs with faulty onboard digital TV which prevented them from shutting down properly, they would either turn backlight off & power light stuck green, or just stay stuck on with no picture.

                  Hi,

                  i can't check the digital feature, because we receive TV via satelite.

                      OK, but what if you just try to switch to the DTV mode, even without antenna, and see if it shows "please tune channels" or "no signal" for example, if it shows nothing it could be indicative of this issue.

                              Sorry for that late reply, but I had a lot to do. Now the TV doesn't start at all and I can't check the digital Interface.

                                  Hi all,

                                  I've got a LG 50PK590 plasma TV which upon plugging in will click three times and the red LED in the corner will come on and stay on, the TV however doesn't come on (no humming, sound, video, etc.) and using the touch controls or the remote does nothing. On exceptionally odd occasions, the TV will come on and work normally when plugged in and will last about 5 minutes before going back to off and unresponsive.

                                  I've got the back off of it and none of the caps stand out as visibly buggered, I've also tested the three resistors in the corner of the power board which...

                                  Philips 47pfl6008s wont turn on
                                  by JorKsX
                                  Hello. Got my hands on Philips 47pfl6008s/12.
                                  Problem is that it does not turn on. Last owner said the problem came slowly.
                                  One day did not respond to remote, had to unplug from AC and then back and it worked. next day had to disconnect 3-4 times before it turned on.
                                  And then it went into hours of unplugging and replugging until it turned on.
                                  When I plug AC into tv, it does not respond to "turn on" button or anything else.

                                  After 10-15minutes the TV starts blinking red LED twice.
                                  So it blinks twice, then waits 3 seconds, then again twice...
