Let me start by saying I am new to the forum and from what I can tell, it seems there are quite a number of intelligent people here. Anyway on to my problem: One night im watching a dvd and I hear a loud "pop" over my home theater, at the same time, my picture goes to predominantly red..... On the surface it seems as though there is a bad bulb in my TV, but if I go into the settings, and select "cool", the color balances out, conversely, if I go back to "hot" the color is red. Is there a sort of "high beam" "low beam" bulb that I may have in my TV? BTW, I have a Panasonic 57" rear proj. don't know the model off tha top of my head but it's only about 1 1/2 yrs. old. Any help would be greatly appreciated. Thanks
