Probably have an intermittent component, or a bad connection on the printed circuit board somewhere.The best advice I can give you would be for you to call an authorized repair center and let them check this unit..

Hope that helps..........

Try leaving set unplugged for one hour or so, see if this clear the problem.

    By unplugging it for a while and draining power from TV you reset it, this can solve the problem if some chip (eg. the jungle chip inside) is jammed with wrong settings.
    If this first attempt did not work, then as already state, the TV safety protection circuit is turning TV off to cause further damage.
    Common reasons for TV turning off after 15 20 minutes are overheating, or overvoltage from one of the boards or of the ICs.
    With no diagnostic code (eg. blinking code) it is impossible to troubleshoot in detail from here.
    As said you need a technician to fix this.
    You can call the phone number listed in your owner manual, call a local TV repair, or tell us your city and get a repair phone number in your area.

It is the protection circuit that has been activated. This is caused by the the overcurrent detection system that flags the protection ciruit to shut the set off.

This is caused by one of the many sections within the tv that has a shorted condition which is drawing too much current.

It requires a pro tech who can diagnose the set, taking measurements to determine the location of the problem.

Very common causes are power supply, high voltage, deflection amplifiers and convergence circuits. The repair is very expensive about 80% of the time.

But, in the case of big screens, the repairs are always over $200, Sorry to say.

But, you really need to get a good tech in on this one.

My RCA big screen plays for about half a movie and picture dims then shuts off. Sound still works. I shut off for a few minutes picture comes back on and shuts off again after few minutes.


These units are famous for loose connections around the high voltage transformer and also bad capacitors in the power supply. The deflection PCB has to be removed to fix this problem. You probably would need to have a repair shop check it out for you. Thanks
