This set has a few common problems that come to mind, but if you have not worked on printed circuit boards or do not know how to read a schematic, I highly advise you to find a local service depot for the repair of this set. Being that said: CHECK FOR 12 VOLTS DC (AC-OFF DETECT) AT PIN 3 OF PC9A21 IF MISSING REPLACE PC9A21 PART # 268P058020 ON THE POWER PCB.
CHECK FOR OPEN FUSES F9A04 AND F9A05 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB. Good Luck, and let us know how you made out.
