I have run into a problem with my home theater set up. I have a Onkyo TX-SR607 receiver and have have my cable box assigned to HDMI 1 in and my DVD player assigned to HDMI 2 in. Then HDMI out to a Samsung tv. Everything has worked fine up until a few days ago. While watching a DVD, The video portion went out and my tv was showing "no signal" yet the audio was working fine. I unplugged the HDMI out from the receiver and then back in, and after a few seconds, everything was working fine. Since then, it has done the same thing a few times. As far as watching the cable box, it didn't seem to happen. That was until yesterday. Now whether or not it's on cable box or DVD, i receive no picture for either, but the audio is coming thru fine. Anybody have any idea what the issue could be, before i have to send it off for repair?
