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.

Although I am not incredibly familiar with your model, There is most likely a small board mounted above the others near the crts, there is a small red connector with a blue wire if you unhook it it will remove power from the convergence IC's and if they are shorted it might come up with conv out, will need a new module.

Hi, this TV is repairable and you will have to replace two devices. the first is the Convergence board. this device regulates the convergence of the RGB stream so it can be projected evenly. it works in conjunction with the CRT's and deflection assembly and the Focus pack(module). The second device that will need to be replaced is the Focus pack(module). This module is malfunctioning and is causing the smudges and warped look at this time.
Replace these two devices and it will fix this set. i will post the Part numbers below along with there respective prices as well.
Focus Pack(module).--- Part Number-- BP59-00005A--- $38.95
Convergence Board assembly--Part Number---BP94-00383A---- $165.95
Please rate and god bless:)
