JVC TV Goes off after about 5 seconds.

I have talked about this TV b4 but i could not give enouth details.
This TV powers up but goes to standby after about five (5) seconds. I
can hear and feel the flyback switched on for that short time. The
model number is AV-20N10 . The micro processor is MN1873287JE

I'm Suspecting the u-com (micro-processor). Can anything else be the
problem?
Thanks all good pals

Hello,

Hmm, no. I'd rather suspect the power supply. Did you check
all the caps in the supply (ESR, capacitance) ?

DId you see full raster before shutdown? I have one at home now that
shutdown when the Vertical output IC failed. New IC and caps around it
and it was back on line.

Chassis number?
5 seconds exactly or variable?
may be a sort of timer? your set has this feature?
