Question about Sony STR-DB930 Receiver
Check all of your speaker connections... usually the PROTECT cuts in when speaker wires get crossed or you have blown a speaker.
this PROTECT message also shows if the amp chip(s) have blown in the unit

I have had this problem where the unit was going into PROTECT mode. This is typically caused by the relays and perhaps some other components developing dry joints over time. I had a professional refresh the solder joints and it works perfectly now

The fuse blowing is a symptom of something seriously shorted internally. What preceded the initial problem? Smoke is bad. Fire would be soon to follow without the fuse blowing. Take it to a tech.
