Re: BN44-00274a dead

Ok, the NTC had me confused. It is same as a resistor. Still shouldn't pin 4 have 18+ volts on it to start and power the circuit? O/P said there was .35v

Re: BN44-00274a dead

quick follow up - put PSB in tv and set powers up perfectly. Believe all the bad solder joints (lot of them on PSB) killed the standby circuit. Thanks to all for the input and help.
