I've started troubleshooting this issue. I've cleared the code and it resets the error. Trying to figure out an approach. Looking for DC voltage in the output would seem the right move. First, determining which channel Front or Surround. Secondly, where to test? I would usually test the pins on the output relays, but they are on the bottom of the main board. Any idea the best place way to check the output?
I know you can disarm the auto shutdown by removing the harness BM502 between the Main and digital board. I've already inspected the board, tested main caps, and diode tested the power transistors.
Any good tech advice on approaching this DC protect problem would be appreciated. The troubleshooter in the Service Manual doesn't get you too far.
