Question about Sony STR-DE485 Receiver
When it's on ( protect )
You can try tighting the ground screws that hold the circuit boards and heat sink to the chassis, But more times than not it will need a pair of output transistors replaced (and a few resistors). This is a job for a pro. A rough estimate is $100-$130.
Sorry for the bad news.
