Re: DC on output Pioneer VSX-1021

Thanks for the tip - will do and report back.

Cheers.

I have this amp in protection mode, its a Pioneer VSX-1021, the MCACC light is flashing. Service manual says it means DC on the output.

I pulled out the amp board and tested the transistors, found they were all ok, except for FL. I found the main power transistors are both shorted, and also the pre-driver stage same channel. All other transistor tested OK in circuit. I pulled the same transistors off SBL (Surround Back Left, its a 7.1 amp), thinking that would get left and right working, until I buy the replacements for the surround later. Left Surround channel left with no transistors...
