Marcus,

1/ get service manual for your serial numbers, Tekwiki, BAMA archive, for free pdf, or Artech, Qservice for pdf, cd or printed version, perhaps 10-50$

2/ open unit, find and replace battery, inspect for leaking SMD lytics, bad PSU caps, shorted tants, overheating parts

3/ input mixers are susceptible to overloading, symptoms no response only noise.

Bon Chance

Jon
