    I don't think its the cable. HDMI cables either work or they don't. If there was a problem with the cable I don't think you would see it on just one part of the screen. Do you notice it on all sources (cable and Blu-ray) or just one? Is it ever on the screen long enough to trouble shoot it? For example if it comes on the screen when you are watching a blu-ray, could you try unplugging the cable going from the Denon to the TV and connect it directly to the output on the Blu-ray player to eliminate the Denon as the cause? I would also try to take a picture of it next time its there.

    If it happens on all sources then its either the Denon, the TV or the cable. If its on all sources and you still see it if you have wired around the Denon like I suggested then its the TV or the cable. You could get another inexpensive HDMI cable and see if it goes away (Try a Blue Jeans cable from Amazon) or call Panasonic. If it goes away when you route around the Denon, then its probably the Denon.
