Have a 27" Proscan that works fine once you get it to come on, but
intermittently will not start up. When it won't start there is no 143 volts
standby voltage. There is raw 150 volts, actually more like 160 volts.
Haven't yet found any shorted or open components in regulator circuit.
Any tips on what is the most common component failure with these symptoms.
Thanks.
