Hello, sorry to hear you are having this problem. Often, (depending on size and model) larger projection TVs can have a switching power supply unit similar to a computer that powers it. These units can make noise at times, especially if the fan gets stuck with dust, it can get stuck and squeal or whine. However this can also be caused by an internal short in a picture tube circuit. It may be that replacing that power supply will fix the unit. Can you provide the full exact model number and type of this TV? Also do you know if / is it possible the TV may have gotten wet inside? Power surge? Knowing that can help solve the problem.Hello, sorry to hear you are having this problem.

Do you know which belt is making this noise? Usually it's the power steering belt, and sometimes it's the alternator belt. The power steering belt will make noise turning the steering wheel when stationary, the alternator belt will slip as you quickly rev the engine by blipping the throttle. In either case tightening the belt to the specified tension will fix the problem.
You probably have a bad wheel bearing or bad tire on left front. when making right turn left front wheel wil spin faster than right making noise louder.
Thats usually a sign of the flyback or HV Splitter nearing the end of their operational lifespan. However its not an exspensive fix unless done ay a repair shop then it can be a few hundred.
