Question about Sony STR-DE475 Receiver
Protect mode with nothing connected indicates an internal problem. Most likely one or more output transistors are shorted. This is a common problem with these and can easily be repaired by a shop for around $35 in parts plus the local labor rate. The output transistors are MN1620 and MP2488 (if memory serves me correctly).
