Re: lines through piture

the colorwheel can cause some color distortion, but malfunctions like the ones you mention are more often a problem with the digital video board. Is there a way you can post some pictures of what this looks like so we can determine whether or not this can a DMD board issue?

Re: low resolution and dim hlp 5663wx/xaa

A lamp provides the "Back light" for the projection, so the only distortion it can cause it the actual brightness. Parts most commonly associated with distortion on the screen can be a DMD, digital video board, or if you have some color disfigures, a colorewheel.
