WTF! I didnt have this issue once with my old TV. Bought a new Sharp LED, it is hooked up by HDMI cable. Everytime I switch inputs to my PS3, and switch back to the TV, the cable box coverts out of HD and into 480i. I have to manually go into settings in the box and force it to 1080i. What the hell is going on? Help please!
