I am hoping some has a print of the power supply on this set. There is no relay activity when power is applied. If I jumper the relay the set starts up with a blue screen. I have no 12 volts present on the primary side of the relay. This set uses a STRS6301 regulator. The power supply is on a separate board from the main chassis. I have checked all the caps and diodes in the power supply. When the set starts up the waveform looks clean and is vary stable at 135 volts so the regulator seems ok? thanks for any help, Bruce.
