My denon receiver has been great ever since I first purchased it on amazon years ago....but a few weeks ago it started to act funny and bad. I was watching a dvd at about -15 to -20, then all of a sudden the receiver just shut off and red light started blinking, I had to go and press the power switch and turn it off then on to go back on again, but it would come on for a split second then repeat the same process of shutting down. It seems like an amp problem to my speakers because if I have the volume to OFF it won't switch off on me, i can pass through audio from multi-out to my tv and video with volume OFF perfectly still, but if i raise the volume higher than -40 it starts turning off, wtf? I can't play anything loud anymore, -40 is not loud. What's wrong with my receiver? Did it blow a fuse?
