I bought a new bulb and still no change.
If the projector is a DLP then it will probably be the DMD chip. The white spots are caused by damaged pixels.

Usually the projector bulb, try to replace it first but I will not recommend you to do so but it is your decision.
SOURCE: Fan noise loud, bulb burst. Replaced with new bulb. Noise even louder! Unit shuts itself off.
the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.

it's the fan. if it won't spin full power, it can't cool down the projector and it'll shut down. there are 2: 60mm (part # 526-0153-00) and 80mm (526-0152-00). both can be purchased from infocus or an infocus service center.

the colorwheel motor does burn out after a while (from heat and dust), but as long as it spins at the right speed, you won't see a problem in the image. if it's making noise, it's going to go soon. it does need replacing. however, infocus does not sell individual parts for the x1 optical engine. you will need to replace the entire engine, which costs up to $2000. so, enjoy the last few hours with your machine and look into getting another.

Hello,
Unfortunately the discoloration is caused by the extreme heat generated by the Lamp has burned the LCD optical polarization filter/elements.
The only solution for this is to replace the entire LCD optical assembly.
Sorry for the bad news, :(
