Question about Projection Televisions
SOURCE: HDTV Rear Projection
The color wheel is the most common problem when it comes to noise from DLP's. To determine if it is a color wheel or fan: Turn on the set. When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is bad. If the noise goes away after one to one and a half minutes after the set was shut off, then one of the fans are making the noise.

That issue is caused by the convergence chips going bad. They both need to be replaced as well as some of the resistor may be bad. To fix the board it usually runs around 300 to 350 dollers. You an order these parts yourself on the net from several places and they have instructions for the replacement of the boards or the convergence chips.
