Weird RCA TV Problem

[Brad]

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.
