    This is a weird problem. When my Panasonic Plasma is turned on after TV is cold (off atleast a day) everything starts out normal. After being on for about 10 minutes I lose the picture. Picture returns after being dark for about 10 minutes. (Can vary from one minute to a few hours. Usually a few minutes) Everything else is normal. Once the screen returns no problem.
    Occasionally the screen bounces then does dark. May go from completely dark, to bouncing, dark again then return to normal. Bouncing only lasts a few seconds. It will either return to normal or go dark. This only happens when the TV is cold. Had this problem for over 2 years, usually when gone for at least two days. Run it everyday for at least an hour, no problem.
    Sometimes it was stay dark for longer. Remote and sound works fine. When screen is dark, nothing appears, even if I hit the menu button. If it goes dark for a few hours and doesn't return, I shut it off. Turn it on the following morning, picture comes on. If it goes dark after 10 minutes, it eventually comes back. Everything else is perfect.
    Any ideas? You can email me at Triceco@aol.com. Thanks.

When it is warm, shut off, then after take a rest it will automatic on again, probably you need change the on anf off switch.

    you said you spent $400 more to fix the problem, but it still have the same problem, fix the switch, you have to contact panasonic company parts' department and give them your TV year , model number,serial number plasma 42 TH-42 px75u, to order the switch and change it. different model different switch.



    You must understand this is my suggestion, usually the TV repaire shop has to use different kind equipments to test your TV before they fix it, I also suggest you, that you can try to get second opion, maybe still have other unknown problems.



    Good luck.

RCA D52W20 TV powers on fine, then shuts itself off after 5 - 10 minutes. After 20-30 minutes, I can turn tv back on, but then shuts off again in 5 minutes.


it looks like the problem is in the 16v line..try to take it apart..and there's gonna be a 2200mf cap leaky.
that will solve your problem.

Tv shuts off after 10-20 minutes


its not the problem with ur electron gun tube or with any picture ic or sound ic. Every t.v. is microcontoller switched machine.
any damage to microcontroller ic that controls the switching will lead to this kind of problem.
0.01% chance of residue EHT voltage would have affected the microcontroller.
