Dlp has dark blue areas on screen

I have an Optoma 51" DLP. The tv was left on and they cable box turned off for several hours while I was out. When the cable box is off the picture is a real dark blue on the screen. The next day I noticed during the news program there was a blue shadow covering the screen where it should have been white. And its very noticable when I watch a movie where the scene is dark, its too dark. Is this repairable, or am I destined to watch every thing in blue haze?

Re: dlp has dark blue areas on screen

Have you tried magic focus? if that doesn't work
replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years

A couple of suggestions, if only on cable and using a box disconnect the set and box from power and after several minutes repower and see if a reboot helps.

The two models listed here both should also have a soft reset done with the original remote and the set on---Menu,1,2,3, enter.

Signs that the bulb in a dlp is going out

A DLP Lamp will fail in two ways. 1.The glass tube housing the filament will shatter and the TV will not turn on. 2. The lamp has many hours of use on it and will gradually grow dimmer. At no time will the lamp cause any picture defect. Check your Cable or Sat box for the correct aspect ratio as well as the TV aspect ratio. Chances are the aspect ratio in either system is set incorrectly. If the gray borders are uniform then the aspect ratio is not set properly. If this occurs on certain channels but not others then the particular channel is broadcasting in the 4:3 aspect ratio and there is nothing wrong with your set.

Mitsu 65" DLP-picture seems washed out

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.
Good luck.
