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 205A3304 I'm Suspecting the u-com (micro-processor). Can anything else be the problem? Thanks all good pals |

Hello,
I'm Suspecting the u-com (micro-processor). Can anything else be the problem? Thanks all good pals Hmm, no. I'd rather suspect the power supply. Did you check all the caps in the supply (ESR, capacitance) ? Adrian |

New IC and caps around it and it was back on line.
