Question about Projection Televisions
What you are probably describing is a high pitch squeal. One can correct it by finding out what part is creating this vibrationm, apply pressure to parts in the high voltage circuit with a plastic device, and apply a silicon to that part. Some times by securing (tightening) the screws on the TV's chassis can stop this.
CAUTION: One has to be very careful if you try this on your own. I would recommend that you call a factory authorized service dealer to repair this for you.
Comment; sometimes the part has to be replaced.
