Ok Have had my 3311ci for a few years now. I have my cable box, PS3, Xbox 360 all HDMI going into my Plasma. Has worked flawless. Past few days I have noticed when I turn on my xbox and PS3 i get white and green lines that flicker and then a quick white box flash. Hard to explain but it won't stop. I have the latest firmware and it does not do this with my cable box. Just the PS3 and Xbox. Its drriving me nuts... Screen will even flicker on and off. Anyone have any thoughts?
