Weird RCA TV Problem

Hi,



Has anyone fixed a late model TV (mfg 2005/2006) with this problem:



You turn on the TV, after the screen lights up, etc. the TV turns itself off. About 5 seconds later, the TV turns itself on, etc. You have to pull the plug to stop the off/on cycle. Sometimes, you turn on the TV and it will play for a while before this off/on cycle begins.



IMPORTANT: The TV may work just fine for a few days, then it happens. Eventually, the TV begins to work fine again for another two or three days before it happens again.



I have serviced TVs for years and I performed many tests on this RCA TV, chassis M134C (mfg 01/06).



I thought about replacing the micro or the eeprom, but I could be wasting my time and money?



Thanks in advance, Brad

Not sure have a RCA authorized servicer have a go at it, presume you do have the service literature (very limited) or look as some of the web sites. S.A.

Hi,

I finally found something that may be the cause of this problem. I will report back in a week or so after I confirm it.

This was the first test I performed >Hi,

Hi, It looks like the problem is fixed (see below for details).

This is the first time I have encountered a button switch/s that tested good (no "leakage" at 50V test), but turned out to have intermittent "leakage".

Thanks to everyone who offered their help, Brad
