Happened a few months ago and after 20 minutes it was alive. Worked fine till 2 days ago, then it came back and then not.

Not much time to check but it has to be the power amp. All radio functions. changes stations and in the dash just no sound. I have been busy so haven't checked anything yet, did disconnect the battery for a while but no change with the radio.

Possibly a bad fuse but where would it be?
