Found the answer to this problem. I had this issue and it just bugged me. First thought was that my charger was bad or the s-video cable that is hooked to the TV. So I switched s-video cables around,same thing. So I started messing with the charger. Tried different plug-ins,with a surge protector and without. Unplug the charger and the problem goes away. So I thought about cutting the ground off the charger to see what that did. Instead I tried one of those 3 prong to 2 prong things you have used before. Problem solved! Sounds silly maybe this whole post but I thought it might help somebody.
