Color alignment is off

Hi. My projector displays a 1/2 inch blue line down the right hand side, and a 1/2 inch yellow down the left. The color alignment seems to be off for the whole display. I have taken it somewhat apart, but is this an easy fix? Anyone know where I can get an internal diagram?

Re: Color alignment is off

I also have the exact same problem. i picked up 3 of these used for my work and kept one at home. I knew one had issues and another had a burned out bulb and so on. I had a repair place to combine the two to make one good one. The repair man said that they had a real hard time keeping the color locked in alignment. It's not a physical alignment, its controlled by the board output and somehow the board can be adjusted. It was vague to me. After about a good couple of years of hard use the one at home is now doing the same. On one hand I want to fix it but I dont even have a plasma so I may go and spend $800-$1000 on a hi def DLP. At that price it won't be the best but it will rock this projector. that would be my advice rather than putting more money into this old model.

Hi there, my dell projector 1800mp is not projecting an image on screen and it only black lines across. what should I do to fix it?.

After turning on the projector, press "+" and "-" buttons on the control panel

simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as


Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.

Image is bright but there is a slight issue - on the left hand side a purple line displays vertically. Anybody knows why is this fault appeared and how could it be solved.

There is three LCD in the projector red, green and blue. If green LCD make any fault mean line or dot or dots then screen show these line or dot in purple color:
If line is very straight and sharp edges then green LCD is faulty and need to be replaced.
If line is not straight and faded edges then some thing in LCD block so your projector need service

3m projector color issue!

the light polarizer on the blue lcd panel is fried due to excessive dust and heat. unfortunately, you'll need to replace the whole optical engine.

LP690 projector displaying strange lines

to adjust those mirrors, you need to power down, unplug, remove the top, remove the wires from the main board, remove the main board, adjust one mirror, reinstall everything, power up, see whatever difference it made, power down and repeat until it's fixed. it's quite a chore. if that's not the problem, you'll need to replace the optical engine (which isn't cheap) because they don't sell individual parts.

Color wheel for a 4805

I've encountered this same issue. I had a large Yellow Line down the left side of the screen for a few months. It got bigger and bigger, then one day I was using it and Bam! What sounded like a fire cracker was my color wheel exploding. I also had the rubbing sound, or at least something similar to that sound prior to the explosion. InFocus quoted me about $300 to fix..

take a look here:,1697,1049289,00.asp "... The others, however, have lost portions or all of their blue channels. TI's theory is that the shorter wavelength and higher energy of the blue light apparently causes the organic polarizing material in the LCD to get lightburn much faster. TI showed us a damaged LCD panel that controlled blue light transmission, and there was a large spot in the center that was apparently burned out..."
