First check for any loose speaker wire in the back as this will cause the unit to go into protect mode if the bare speaker wire is touching, if thats not the case then there is a problem with the unit internaly and would be hard to tell whats wrong with it without looking at it.

Check the fuse, Sony is known for its random problems with sound. The one I have you must tap it on the side. Its a flicker switch inside.

Sony STR-DE445 protect displayed


It sounds like a bad solder connection. It just needs to be soldered up, if you take it into a shop just tell them it doesn't need any new parts, it just needs to be soldered up.

Or, if you can solder it yourself, or know someone that can, that would be much easier.

check/replace your speaker wires. If a wire came loose, it will go into "protect" mode and shut down, to protect from a short circuit.
