nekrosoft13 747 Posted September 5, 2015 I used to own an Onkyo that was due for upgrade and I bought brand new Denon AVR-S910W, ever since I got the Denon I been having HDMI issues. first it started with occasional green horizontal lines across the screen, I replaced both HDMI cables, one going from PC (AMD APU powered home theater PC) going to receiver and from receiver to TV.Now when we are watching TV, the TV will occasionally every 20-60 minutes will black out for about a second and picture will return. I have about 20 days to return the unit, if I can't figure out what is causing it, I will have no choice but to return it.My old Onkyo never had that issue.
