A customer just brought this set in, complaining that it shuts down intermittently... sometimes after a few minutes, sometimes after a few hours. My first thought is to check for bad caps in the power supply, but while I'm doing that, I thought I'd see if anyone here has any experience with these and could perhaps point out something I should look for.
The power supply looks OK.... no caps up in ESR, and I resoldered a lot of connections which were marginal at best. The set however is still shutting down at random. I called Westinghouse tech support and they said it was either the power supply or the backlight inverter. The inverter was buried deep within the set so I didn't bother to check it.... could it be the cause of the trouble? I really need some advice on this.... I can't go ordering expensive modules at random, I have to know for sure what I need.
