Hi, folks I've read a number of threads dealing with the protection relay not engaging in a Pioneer SX-980 receiver, but nothing regarding the relay dropping out right after turning on. I assume I've got amplifier issues, but not sure where to logically start. Using the service manual, I did reset the amp board pots to home position for the calibration. I can't even begin to set them due to the protection relay kicking in and out. Any ideas of where to start would be appreciated. Thanks! Brian.
