I have a 2007 360 connected to my Samsung plasma TV with a VGA cable. Recently, the video quality degrades to the point of extreme color banding as seen here:
I've tried to unplug and reconnect the VGA cable but to no avail. I also reset the power on the 360. When I do this, It looks normal for a minute or so, but then it reverts to the banding. How can I fix this?
