Replace the amplifier section, it is ready to **** out on you. This is exactly what mine did. If you have proper ventilation and have a fan on it to cool it you may get some additional time out of it.

Check all your speaker connections and make sure there are no shorts where any of the negative wires can come in contact with any of the positive wires.

Sound quit and display shows PROTECTOR Sony STR-D865

This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic.
1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

Str de 435 I was watching a movie nothing was being moved when suddenly I heard the relay click the protector mode came on thank you

Relay click and Protect display indicates that receiver got problem in output amplifier section and most probably output chips got defective. This kind of problem is not user level repair and local repair shop will help you to get it fixed.

Volume change, followed by slight static playback.

I believe you have dry joints in output drive it require a qualifier Technician the do this you need special soldering station with anti static you are dealing with surface mount components if you shorted some thing in output drive it could damage to the output they are expensive to replace, now is not too bad you should bring in to Sony or servicce center Sony to repair it

It shows protector because the unit detects a short in the amp section of the unit. You will need to trouble shoot the amplifier section and replace the bad parts. If you have no solid state repair experience, my best advice would be to have a pro take a look at it for you. Good luck
