Replace the 15 Volt rectifier diode and check the electrolytic caps in the
regulator circuit.

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.
