Yamaha RX-V1500 will not power on

I've had this receiver for a year or two. Does not run hot. Never had even a hiccup from it. I usually just leave it on 24/7. The other day, when I was near by it, I heard the fan running. Indeed, it was powered on and the fan was running. I hit the power button and turned it off. I thought this odd, the receiver had never ran very warm and I had not known the fan to kick on. I then realized that the past couple days, I had heard that fan running on occasion, and did not realize that it was that fan. Some time, the next day or so, I put an album on, and it played about half way through the side, and the receiver powered itself off. It would not power back on, so I unplugged it for a few minutes. I plugged it back in and it powered on, but powered off pretty quick. Then , it would not power on at all. A couple times, I got it to power on by holding the speaker button, and then holding the power button, but it would power off right away. Now, it has reached the point where it will not power on at all, and I have removed all the speaker connections. Any ideas? Maybe a fuse gone bad?

Being an A/V surround unit. I doubt you'll get a big response on these forums. And no Service manual? However.. Not the Fuses but probably in the power supply as it seems the unit gradually fell off. Just gotta do some testing. all starts from power cord power switch to transformer etc..
Might be voltage reg. chip in the p.s. region. Another is a shunt cap in the o/off switch circuit when open.
