CD/Radio stopped working in my winter beater

The entire unit completely shut off and I cannot turn it on at all…it’s like it’s not even plugged in.

Can head units just die out of nowhere??? I put a test light on it last night at the harness that plugs into the head unit and it is getting power. The fuse on the head unit is not blown. I don’t have another head unit to wire up…my next thought was to grab a factory radio from the jy and sell the car.
