Mine will turn on for a few seconds then whill shut off again but the standby light would stay on
The only thing to test would be to disconnect all speaker wires at the receiver then turn it back on. If it still won't turn on, it's an internal power supply issue and will need service. If it turns on, post a comment and I can walk you thru further troubleshooting. Hope this helps
