TV Repair Questions? Ask a TV Technician for Answers ASAP
Turn the TV off and make the room as dim as possible. Then put your face down by the lamp housing and turn the TV back on. The first thing you should hear is a spinning "whirrr" (the color wheel). Shortly thereafter, you should hear a crackle "bzzzt" (the ballast). At the same time, you should also see a spark (very small blue flame) at the rear of the lamp housing. Do you hear the color wheel and hear/see the ballast firing?
