Modern home-theater components monitor themselves electronically for potentially dangerous malfunctions such as damaged internal parts. When a unit's microprocessor senses a problem, it will typically shut down so that no further damage -- or potentially dangerous disasters like fire! -- occurs. Your receiver is identifying something upon turn-on and shutting down as a result. My guess is that you're going to need service for your Yamaha. There's likely no fix that you're going to find. You need a professional service technician.
