We have a problem with my daughter's hi-fi system, the push power protect message appears even when the speakers are unplugged, it is a Sony CMT CPX1. Thank you for your help.
same problem. hoping someone can help us. for me, it powers on, and as soon as I turn up the volume, it cuts off in protection mode, whether with or without speakers, it doesn't make any difference at all.

Just use the remote control!!!! turn on the channel manually, then turn it off with the remote control and turn it back on with the remote control.
