The color on my mitsubishi model # vs-5041 is faded and foggy.


Hi, did you try a color convergence? I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:

Color wheel replacement


With the back off of the unit, you are looking at a silver can on the light engine. The is the board where the DLP IC is located. There is a large heat sink right in the middle. Near that heat sink you will find a small square cut out where two pins protrude from the inner bd. There is a small black piece across those two pins, that is the jumper. With a needle nose slide that black jumper off of the two pins. Normally if the color wheel is changed and the jumper not remove the picture is very poor with ugly green and purple negative look.

Phillips Magnavox 60 inch Projection Tv


That model is famous for having bacterial contamination in the CRT coolant causeing halos, and dim pictures with bad overall color issues. You can look into the lens of the CRTs when the set is laying and if the coolant looks cloudy or has any growth there you will notice it right away, and changing the coolant will restore color, clarity and brightness.
