I bought a used projector. It works fine bit it has a square box right in the middle of the screen. Sometimes it is green but mostly it is yellow. Can anyone tell me what could be wrong and how it might be fixed. Thank you
if it is the size of a pixel then what it sounds like is a burned out pixel which meens you have an LCD projector. Nothing you can do. Most warranties allow 9 or more per unit.
Yeah,as mentioned, if it is the size of one or even a few pixels, it could be them burned out. If its not a smooth edged image it could be dust spots on your projectors LCD units.
