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?
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.

You can adjust the lines and make them straight. You can also in the same process, make them line up.
1. With the TV on, press the mute button the remote control so that you have picture but no sound.
2. With remote in one hand (holding it as far from the TV as you can but still be able to reach the TV with your other hand), press and hold the mute button again, with the other hand, using the control panel underneath the screen, press the menu button on the TV set.
You will notice an "S" on the screen on the right hand side about 2/3 from the left, halfway up the screen (If you did this right).
This means you are in service mode.
With the remote, curse right only once and you will have some information displayed in the upper left. The top line is Item, the one underneath is Data.
Press "7." This will display the built in cross hatch pattern. You can move the line around with the directional circle located at the center of the remote. Using the "3" button, you can decide which color to move. To move the curser to a new location, The number pad doubles as a direction key pad. (2-up), (4-left), (6-right), (8-down). To simplify the process, you can eliminate the red or blue or green lines and only focus on one color at a time. "0" will shut on/off the green line. "100 button" will shut on/off the red line. "CH RTN or Enter will shut on/off the blue line.
"7" will exit the process as well as get you there.
Power off when you are done and turn back on.
Repeat as needed.
Here's the deal with the cartridge alignment page....the machine will spit out a series of black lines mixed with yellow ink and at the beginning of each of these lines is a "Green" check mark. The carriage moves back and forth over these lines and green check marks and reads them by use of what is called a "spot sensor" that resides on the right side of the carriage assembly. This is usually noticed by the blue ray of light that shines out of it. So if you are getting an alignment failure one of two things is happening....1)You've have got a bad cartridge (usually the color) and it is not laying down the right colors, specifically the green check mark or 2)You've got a bad spot sensor...even though it may still be shining the blue light, the sensor board can't process the information. Its an easy fix either way.
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.
take a look here:
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..."
