Hello!
Went into my Fisher RS-1056 stereo receiver to troubleshoot the damaged meter...
annnnnnnnnnnnnnnnnnd in the process while the unit was powered up(trying to move meter cover to get at actual meter wires) I touched the cover to one of the transistor's heatsinks. Unit shut down. Took cover off. Unit restarted. Touched cover back. Unit shut down. Repeated said process 1 more time(trying to figure out what's going on) and all of a sudden the unit dies and will not restart. Main transformer is good. On the main power board, there is the proper voltage on all pins EXCEPT for pins 3, 4, and 5. Tuner is totally dead. No voltage leading to resistor R01. Ditto for resistors R04 and R05. All fuses are good and the audio transistors are getting power.
I'm stumped. Please help.
Thanks.
