Question about InFocus LP120 / 1000 Lumens / XGA / DLP Projector Refurbished Multimedia Projector
I have a brown "bar" running down the side of the projected image on the screen. It almost looks like a burn mark...but is not on the computer screen just the projected image
That is caused by a collapsing light pipe.
This is a mirrored glass square component that is located directly behind the color wheel. It is comprised of 4 mirrored section approximately 40mm x 8mm that are glued together with a hi-temp adhesive to form a square. The artifact you see is one of these mirrored glass section's has come unglued and has moved inwards blocking one edge of the image. The edge of this shadow is not shar because this failure is not at a focal point.WHEW..all that being said it's possible to re-glue it if you are electro-mechanically savvy and have steady hands. If you need to take it to a service they will most likely just just replace the complete DLP engine (the whole optic assembly) Hold on to your wallet!!
