Power

Can’t turn on the AV receiver

•Make sure that the power cord is plugged into the wall outlet properly.

•Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it back in again.

•The amp protection circuit has been activated. Remove the power cord from the wall outlet immedi- ately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord discon- nected for 1 hour. After that, reconnect the power cord and set the volume to maximum. If the AV receiver stays on, set the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources.
