I’m going to take a crack at repairing my Premier. It popped all the fuses on the source components that were in stand by mode when I turn on the Premier. I can see burnt SMT on the regulator board (R39,R40, Q11,Q13,Q14,D13,D14). This may have been a common problem with this model as PSA used to sell repair kits for this. The unit still powers up and I’m getting 120VAC on the receptacles on the back. I’m waiting on my parts order . Any suggestions ,tips . I didn’t order new power transistors or the big capacitors yet.
Do you already have the schems you need?
