Yamaha R-N803 has no power
I went to turn on my Yamaha R-N803 amplifier after moving it to a new location. When I pressed the power button, there was a pop/bang sound and a flash inside the unit. The standby power light turned was on for a few seconds and then turned off. Now, there’s no response from the unit at all. When I turn it on, absolutely nothing happens. No sound of relays, nothing on the display, etc. Completely dead.
Maybe I blew a fuse? Where should I begin looking for problems? A quick look inside the unit doesn’t show anything obviously wrong, but I’m also not sure exactly what to look for.
EDIT: A bunch of photos of the insides. I also tried replacing the fuse on the power delivery board, no dice there. The original fuse is just fine as well.
The whole thing:

Everything else:
Esta é uma boa pergunta?

Make sure you'll have access to a multimeter (yes, inexpensive department store meter will work ;)

@oldturkey03 - thank you so much for responding to my post. I realize it's been a few months since I originally posted it (life got in the way and I completely forgot about this), but I've added a bunch of hi-res photos and a few other details.
