I have a Sony KDL-52XBR9 hooked up to a Denon receiver with HDMI. I have my Motorola Cable Box and everything else ran to the receiver. I have had the screen on my TV go completely green several times. When I turn the TV off then back on again, it seems to fix the problem. I called Sony last night about it and they said they are aware of the Motorola Cable Boxes doing this. I find it weird because my Samsung has never had any issues with the Motorola Cable Box. Has anyone else had this green screen issue before? What should I do? My warranty from Sony expires on Dec 5th.
