I purchased a 360 over the weekend. The problem is when I change the input to go back to viewing tv the tv flickers in and out. The picture is there for five seconds then goes black for about 3/4 of a second then back to tv for five seconds and so on. The tv is a 42" Pioneer Plasma. Has anyone heard or experienced such a thing? I am about go call customer service right now but I honestly can't remember the last time a customer service person helped me with anything.
