You'll need to use an electronic swab, and use air to blow out the loose dust particles.

The images displayed are purple. I sometimes solved the problem by adjusting the focus. Now it remains purple all othe time.


Hello...The problem you're describing is related to the green lcd and most likely the main board(green channel). If the focusing removes the purple(you have *that* much dust in the unit?) then it *is* dust. You should be able to focus on the dust particles twice--dust on the front of the lcd and dust stuck to the back of it. I'm gonna give you the color table so you know what to look for and what you're seeing. Red LCD=cyan(baby blue) onscreen; Green LCD=violet(purple) onscreen; Blue LCD=yellow onscreen
If you have a lot of dust(and the green lcd usually is the main culprit by the design of the lcd panels around a glass "cube" internally) you might try blowing some air into the unit when it's cool. However, the unit probably needs a good cleaning--remember to clean the dust filter! To properly clean the unit, a trained tech will have to perform the job. The lcd panels are DELICATE and precisely positioned for displaying a sharp image.

Projection has yellow tint


From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

Yellow spots on the projected image


Hello there. First, some info you need...Green LCD=purple onscreen, Red LCD=cyan(baby blue) onscreen, and Blue LCD=yellow onscreen.
These spots (specks?) are probably dust particles that get past the filter. Annoying but harmless. To check if they are indeed dust bits, if you can focus sharply on them, then yes, its dust. To remove the particles completely will require a service. They will only return eventually. You can try to blow out the biggest offenders with some canned air. And, to help slow down dust entry, keep the dust filter cleaned so that the unit always has plenty of air movement--you'll have a cleaner image with the added benefit of LONGER life of the lamp and projector components (dust is the number 1 killer of projectors)

There are blueish-purple crystal-like distortions in the projected image. They actually can be brought into focus to look at, and at that point the projected image is extremely out of focus. So, obviously,...


either there is something on the inside of the lens, or there is something on the lcd prism face. if it was the lcd panel, it would be in focus with the picture. take it in for a good cleaning.

This is probably the polarizing filter. It will need to be replaced. It should not cost very much to fix.
