Summary: HDMI switching does not work properly - picture changes color,flashes. Took it in several times to the shop and they have given up on it. No longer use the HDMI switching, I use it in a room with a tv that has 4 HDMI inputs so it isn't necessary.
Summary: I purchased this unit in June of 2010 and noticed right away that it ran hotter than most receivers, but it seemed to perform well. Less than a year later, this unit no longer picks up the signal from the HDMI sources and even after unplugging and resetting the unit several times, no sound comes...
Summary: I purchased this unit for a new home theater we were putting in our basement. I took a chance with it because I had an Onkyo receiver in the past and it worked flawlessly. I hooked this unit up and when I started playing a movie, the audio would cut out ever 3-5 minutes for 10-seconds or so.
Summary: I bought this after a decent amount of research, but with A/V receivers, there are always a slew of good and bad reviews with each one. Well, here is one more bad review for Onkyo. I installed the whole system, and then got the thing hooked up to my tv.
Summary: I read the reviews before i purchased and chalked up the bad reviews to hopefully a bad shipment. I had faith as i owned an Onkyo for 10yrs that worked flawlessly. I wasn't that lucky with this one ... 2hrs into using it the picture began to flash then eventually went black.
Summary: I hooked up the new Onkyo in about an hour and it sounded great! The next day it wouldn't work for anything hooked up through the HDMI input/output. I called Onkyo service and was greeted by an unhappy tecnician (well it was a Sunday)who told me to reset the Receiver.
Poor Customer Support, Did not properly pass HDCP handshake

Summary: Purchased this unit to complement our home theater projector. I was mostly looking for HDMI switching and good sound quality. The upconverting from analog etc was not important to me so this fit the bill. Received the receiver quickly as alway from amazon.
Summary: Would never recommend this receiver and I'd lean away from Onkyo products in the future. My 608 model seems ok so far but I'd never recommend a 508 in the future again.
Cons: HDMI was the purpose of this receiver and the receiver has HDMI handshaking problems galore. DVD playback on a blu-ray player blacks out. The OSD no longer outputs to tv- the tv is not receiving a signal any longer. I purchased this receiver in May and have had problems with it ever since.
