Check IC LM324 on Front Panel PCB L1791-FP-CNT-1203.
It might be Damaged.
Check the voltage Potentiometer. It might be Short.
Check Voltage Selection Preset R22 on Front Panel PCB. It might be Open.
Check Preset VR1 on Pre-regulator PCB (PS-PREG-1791-0903A).
It might be Open.
Check whether Auxillary Transformer Windings are reaching PCB.
Check whether there is proper contact between Load Terminals and Terminal
Nuts inside the Unit.
