No if the problem is the screen, you will need to replace the entire screen assembly. some screens come in two parts. The inside of the screen is called the freznal lens, the outside of the screen is called the lenticular lens. Good Luck

It's either mirror hinge fatigue or dust on the inside.
Mirror hinge fatigue can be fixed by putting a solid color picture (white or gray works best from what I understand) on the display and letting it sit for 20 minutes.
If it's dust, someone is going to have to go in there and clean it out.
Also could be a defective micromirror device.
Try the first suggestion and if it doesn't work, you're going to need a technician to take a look at it.

This is a dmd chip going bad. Here is the replacement on a very similar model. You would need to verify your chip number to be sure. Love to know if it is the same as the 250 and it probably is. http://youtu.be/775YOs-aOPc

LCD projector spots showing up on the screen


there are light filters behind each lcd panel that determine the color of light going through it. because of excessive heat and dust, the filter tends to burn and cause discoloration in the image. if the image is bluish (cyan), the red filter is burning. if it's yellow, the blue is burning. if it's purplish (magenta), the green is burning. the filters will need to be replaced. unfortunately, many companies don't sell individual parts of the optical engine, so the entire engine might need to be replaced.

Yellowing spots on 52 inch LCD Mitsubishi display


have the store fix it you need a tech that has the right equipment to fix that. Since you say you replaced the lamp I assume you mean a LCD micro projector not an LCD Flat panel. There is a piece of equipment that a tech should have that can be plugged into the TVs circuit board and it can fix the spots with an electric pulse. I have seen in done on micro projectors in the store that i work by our techs. So my advise is have the store fix it before your warranty runs out.
