I have this sharp 32 inch LCD TV that appears to be stuck in standby.
When I plug the set into the mains there is no led lit , when I press the on off button on the TV the LED turns red but the tv remains lifeless. There is no remote control function.
at all. The 12 .5 volt rail is only measuring 7.8 volts , PS ON seems to be stuck at 0.2 v. I notice the voltage on the Mains Filter Cap is 343v - 345v slightly fluctuating not a rock steady reading , I am wondering if the PFC is working right.
