Question about Philips ProScreen 4600 Impact Multimedia Projector
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.

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.
