Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty.
The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed.

Try to turn the contrast down. It can really help out a lot. If this is not working look up your tv's best settings. CNET.com has some great settings under the forums.
If all else fails but a calibration dvd and go thru the settings. Some dreamworks and disney dvds even have them right under the disc extras. Hope I could help!
by the way, remember to cut some of the light in your room if it is well lit. It will help make the picture look better as your eyes can distiguse the light and darks better
