I shorted a screwdriver against the heatsink of Q11 on right amp board and pop. Receiver powers up fine and plays on left channel only, all fuses are good. I checked that transistor b536 and it was good, any ideas where I can start checking on that board

I should have added that with both amp boards in speaker relay will not engage. When I remove the right board the speaker relay engages and I have music in left channel. To try to eliminate the issue I put the right amp board in the left channel side and got music. The amp boards appear to be fine. The issue is prior to right the amp board. Thanks

I found a lifted trace burned In half on the power supply board. Soldered together and for now is ok. I have lifted shorted many traces on this unit and was embarrassed to mention another one. On this unit I have done more damage than the initial issue I had which you helped me with Glen. Thanks for the help always
