Question about InFocus LP 600 Multimedia Projector

1 Answer

Internal mirror broken

I have an LP600, and the internal mirror is broken. It is a small 4-sided box that is made of mirrors, behind the color wheel. It was cutting off half of the image on the screen, so I took it apart and found that this little rectangular box had one side out of whack. Upon looking at it further, I found that the glue had just broken and not the mirror itself. Is there a way to fix this, or does someone know where I can get just this part? I didn't pay for the projector, it was free from my work, and I can have it. I just want to get the part or a way to fix it so that I don't have to pay an arm and leg for the repair. I don't have any images to show....

    We had this problem. The nearest repairer is 200 km away - three hours by road. The service agent would potentially have taken minimum two weeks to receive, repair and return. Instead my husband replaced our infocus lp600 light tunnel with a piece of 10mmx10mmx1.5mm aluminium channel inside which he placed a polished aluminium reflector panel from fluoresent light casing cut to fit and folded square. Three months later and we have no further problems.

We have an LP600 with a black fizzy edge slowly sliding into the image field from the left picture edge?


sounds like you have a broken light tunnel. Its just a four sided mirror that has a broken side.

Yellow green display


you may have a bad cable. if it was an internal problem, the menu wouldn't be the correct color. you may also want to reset the settings to factory default, just to cover the resolution issue.

Broken mirror replacement


You can contact a service center and try to get replacement parts. However, if you've never worked on projectors before, I strongly advise against it. The positioning of the internal components is critical for proper image display and focus. Also, proper positioning of mirrors and lenses is critical for heat dissipation. If this mirror was broken due to impact, there very well might be further damage that you can't see. ---rick

Internal mirror broken


Well without seeing the damage I would have thought Superglue would be your answer and just re afix the mirror if it is indeed undamaged .
Otherwise as it has a working bulb ( usually worth more than the actual machine? ) Maybe a replacement unit off ebay can be obtained you would also have a spare for any other repairs . .... Regards Vortash

Infocus image problem


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!!

The light tunnel is between the color wheel and the mirrors. It is a square 4 sided tube, the inside is a mirror finish. the tube is either broken or the glue holding the assembly together has given out allowing the mirror to partially block the light. Advanced repair

LP600 - Grainy picture, very poor quality


Single chip DLP projectors use a spinning color wheel between the lamp and the DMD (mirror chip) to produce colors. If the wheel rotation/synchronization is disturbed, colors will not be displayed correctly.
In my case it looks like the wheel became un-synchronized, probably because the projector was dusty/dirty inside (a light senor is used to detect the wheel position), resulting in a grainy, slightly flickering image.
I simply blew out the components with a can of 'Dust-off' and, using a small tool, rotated the color wheel by hand to make sue it wasn't rubbing or jammed.
I reassembled & started the projector and the image was back to normal.

Infocus x3 video problem


Sounds like it could be the mirror tunnel. There is a very small mirror tunnel behind the color wheel (looks like a long prism) that can often fail as it is very fragile. This tunnel concentrates and channels the light to the DLP chip and if it collapses it can cause the very issue you describe.

1/2 the screen is viewable


You would be wrong. Lamps do not do that. They either work or they don't, they do not cast shadows or give half an image.

What is going on is the light tunnel has failed. It is a small, 4-sided mirrored tunnel that focuses the light into the optical chamber. It is directly behind the color wheel. I've seen this probelm dozens of times.
