Entertainment Center: TVs, Stereos, VCRs and DVDs - Anyone had this trouble before??

My RCA big screen plays good for 5 to 10 mins. then cuts off and won't turn back on for at least 30 mins. at which time the cycle repeats. Something must be overheating,....but what?? Any help will be greatly appreciated. Thanks.

Good Morning, Stan58:

Yes, I am certain someone has had this problem before.

The first place I would check is the High Voltage Regulation of the set. The high voltage to the projection tubes is regulated to some very strict limits to ensure good focus and long operating life of the tubes. If this circuit fails, the high voltage will fluctuate as the picture changes. Darker scenes will allow the voltage to rise and high brightness scenes will cause the voltage to decrease. Once it finds an "out of tolerance" condition, the set's Fail-Safe circuits will engage and turn the set off.

There are other possibilities, of course, but this is the more common failure.

To find a history of the failures and fixes of this set, here is an excellent site to review:
