The clip leds are shunted/switched by a MPS8599 transistor that gets it signal from the FEB modules. The transistor shunts across the led and it base is driven from one of the FEB's outputs. Check Q101, Q102, Q122, and Q123 for proper operation.
The rails should be as below:
P. S. RAILS: HV: +/- 29.5V
HC: +/- 23V
RB: +/- 18V
Hope some of this info is helpful...

Are you sure that you don't have that backwards? The amp can feed all 4 channels with input from channels 1 and 2 but not by feeding 3 and 4 (unless I'm misreading the manual).
