Question about Dell 2200MP Multimedia Projector

Dark Area Growing on Right Side of Image

My Dell is 4 years old and the color wheel was replaced a year ago along with some other component circuit a year ago. The projector is used daily. 4 months ago all images started showing a darker area on the left side (project upside down/ceiling mount) that is growing towards the right of the image. It started as barely noticeable on the left and now it is covering 1/3rd of the image. I was told at a local electronics retailer this was likely the bulb, so I replaced the bulb and it had no effect. The only thing I can guess is this is some lens that is darkening from the heat the more it's used. Any help would be appreciated.

Have the same problem with the shade growing. Anyone one have a service manual so that I can take the unit apart and attempt to correct the shifting lens? How does one fix the position of the lens?

thx

It isnt the lens. There is a crystal asembly that the light is reflected thru after it hits the color wheel. It is 4 pieces of completely mirrored glass glued into a small metal holder. One of those pieces has shifted. To fix it, you can take it out and possibly have a jeweler repair it. It is difficult to take out, but it is doable. Feel free to contact me if you need to. email is (bill @ baerwalde . com) Just remove the spaces.

In some cases,after installing a new color wheel, the speed of the wheel motor must be adjusted to obtain proper speed to ensure a satisfactory image. Unfortunately, you can not and should not attempt to do this adjustment yourself as the service menu contains many adjustments which if accidentily mis-adjusted may cause irrepairable harm to your TV. Ask a local samsung servicer to do an "index delay" adjustment in the service menu.

Samsug rear projection tv, everything looks green

Dust accumulation in color wheel, light tunnel, chip area can cause green tint.

It is very delicate area, light tunnel and chip can be easily damaged. Remove light engine assembly and color wheel. Blow dust out. Re-assemble. If the gasket around the color wheel housing is not replaced in the right position, or the housing screws not tightened correctly dust will contaminate the color wheel/light tunnel area.

Call someone that has done it a few times. If near Calgary, call me.

Red-striped ghost images.

when you leave your TV (no matter what kind) and you leave it for long periods of time on a static image or something.. the image tends to burn in to the screen... so changing the glass would be a way to fix it.... the problem is that that kind of repairmen is more expensive and difficult than buying a new set...
