I just bought a 55 inch 7100. It is replacing a 5 year old 42 inch LG LCD. I have a Denon AVR 1913 receiver. The TV is hooked up with the same cables and same configuration as the old LG. TV input from the Denon, all devices hooked up through the Denon. All HDMI. I have searched the forum, but I have not seen any posts detailing a similar problem to what I am going to describe. The picture looks very nice. But, there is distortion on all devices. The picture bounces and has distortion intermittently. The distortion is sort of a random white noise flicker in seemingly random parts of the screen of very short length. The bouncing is noticeable particularly on things with a static bar at the bottom (e.g., CNN or ESPN). If I bypass the receiver and hook up directly to the television from each source, the problem goes away. The thing is the LG did not have this problem with the receiver. I thought perhaps it might be a cable issue and I have tried various combinations of cables (none of my cables are expensive (mostly monoprice and they were not purchased with a 3D set in mind) but the fact that the problem goes away when I bypass the receiver is troubling. Is this a known issue? I would like to use my Denon video passthru, plus it seems it is the only to get HD audio formats. I pretty much have to have I have too many devices (Apple TV, Blue Ray Player, Direct TV, and Xbox). Thoughts?
