i have a westinghouse tv. im not sure which model it is. when i switch to the hdmi output (i think its called output.. the "hdmi" option on the remote) my screen turns white/silver. it just started happening earlier today. i can be watching tv fine, but when i switch to hdmi to play on my xbox the screen turns whitish silver and wont turn back even when i switch back to tv. its not my hdmi cable, ive tried 3 others i have just laying in my room and i get the same result every time. i can use the regular cable (not sure what its called, 3 prong cable with yellow red white connectors) and it works fine, i just have a horrible picture quality. hdmi was working fine last night. does anybody have any idea what i should try? im guessing i might have to buy a new tv to get hdmi to work, i just hope not.
