My Dell 2200mp projector was
You will found that there are some mirrors (4 of them, making a 'tunnel')just behind the color wheel. I assume these mirrors are positioned tohelp focus the light from the lamp into the first lens element making a sharpand bright beam to be then hit the DLP chip. These mirrors are betweenthe color wheel and the first lens element.
These mirrors mayhave come loose inside the assembly, and may be sliding around. Check ifone mirror was broken on the corner. A broken mirror caused the light is notbeing properly focused on the DLP chip resulting no image as well as themirrors distorting the light beam causing the darkened wavy shadows in the image.
It also couldbe the lamps ballast that is your issue or the lamp counter reset might havegone bad on you. Most dells the ballast would be the problem area. The ballastis what the lamp connects to. That is what powers the lamp. When those go badyou will this type of problems. Check the lamp again, check the lampdoor, and finally check the ballast.

Yes, it can be replaced; but Dell replacement parts are very hard to find. Also, it is tricky to open the equipment and not damage any other parts during the process. If you don't work on electronic equipment, I would take it in for service. Other suggestions on the web say to buy a used one for replacement parts if you want to do the work, because they cannot find service manuals or parts - except for bulbs. The color wheel for my Toshiba was $160, and the lamp was bad at the same time.

This is usually caused by dust getting on the mirrors. You will have to take the projector apart to clean the mirrors. Also I am going to include instructions for Self Diagnostics. Self-diagnostic for video
- Dell 2200MP projector provides self-diagnostic test of the projector
video display (for Video, S-video, Component-I). Use this advanced
feature for preliminary self-diagnostic on your projector when
encountering the display problem for video.
- After turning on the projector, press "+" and "-"
buttons on the control panel simultaneously and release the buttons
when screen goes blank.
- Contact Dell if the projector doesn't enter diagnostic mode
or if the colors are incorrectly displayed.
- Press "+" and "-" buttons again to exit
the diagnostic mode.
- While in Self-diagnostic mode, the screen will run a seven-color-cycle
test as following: "Red--> Green--> Blue--> White-->
Watchet Blue--> Dark Green--> Yellow." Ensure that
the colors of the test pattern are correct.

Projector 2300mp Black band at
One person reported vertical black banding on the right of the screen, and someone told them it was a bad control board. I would contact Dell Support and see what they say. I've also heard of fan noise on these devices, but I wouldn't think that's what's going on in this case.
Here's Dell Support's site:
Good luck, and hope it's just an adjustment.
