Xb31 digital projector

You need to take it to a repairer that handle this projector as you have broken it. There is nothing you can do yourself.

use the projectors menu to set up the correct input source rather than in auto mode.

hope it works.

You should be able to get the part directly from HP. See Here.
enter your serial number or parts code and viola.
If it's not listed on the site. Call them. They have many parts not available online over the phone.

No only a cert repair shop/person can Rsq (remove & replace)what sounds like a capacitor leak

on the back of your projector there should be a switch that says some thing like normal-service or something similar to that
place the switch in service, and a kind of grid lookig pattern should show on the screen
next look for the adjustment screws for the colors, because it sounds like the blue position has shifted on you,
this may be caused from moving the tv, or from bumping it.
the adjustment screws may be exposed to where you can acces them easily, or it may require you to take off the back of the projector and adjust them that way
go very slow with your adjustments, as a small movement may cause a big change on the screen.
if your projector has a separate lens array then you will have to adjust the lens position.
for that, there should be adjustment screws located on the side and top of the lens, that way you can adjust both horizontal and vertically.

if you have the dp6150 (lcd projector), you have a lens or mirror out of alignment, or something obstructing the light from the inside. if you have a dlp projector (not the dp6150), the light tunnel has collapsed and needs to be replaced. you can get the part from an infocus service center (like av solutions in ny), or send it to them for repair. they're really good. www.avsolutionsny.com

The Stress of impact on the imaging forming unit that is directly behind the projection lens has a flat glass surface. If it is cracked the stress cracks would project with any image because they are on the same plane as the image
