Please somebody help...I've got a Denon 7.1 receiver, I've had it for a few months, every once and awhile, when I've got the sound past volume setting 20, the system shuts off and goes to standby, I usually turn the system back on, lower the volume a bit and it's fine; annoying but it works. Today I was listening to it past 20, the system shut off, but now when I turn it back on, the system display gets to "receiver" and then shuts off...happens every time...thought maybe it was just overheated...but now I think it might be a fuse...has anyone had this happen? Any resolution? And...to make matter worse, I can't find my owner's manual...AND I have a slew of people coming in this weekend for bowl games....help!!!! Thank you!!!!
