The red and blue guns of a CRT projector have mounting screws which when loosened allow the two outer guns to swing left/right. The central green gun usually isn't adjustable left/right (another reason to be very accurate when mounting the projector) Up/down mechanical aim is accomplished by altering projector tilt.

Colors are out of alignment


There is an alignment mode that you can get to. You must take off the back cover and look for the alignment switch I suggest that a tecnician do this because he has the propper tools and knowledge. If just an allignment is all it needs it should not cost that much. You have to try not to move this type of tv around because it is very sensitive and the slightest bumb can send it out of wach.

Color convergence alignment


You just need new convergence ICs. Go to this link and leave an email by clicking the contact link on the lower left side and tell them your model number they will let you know the correct ICs you need. then if you order through them they give free installation instructions and free on-line tech support so you can instant message the tech while you do the repair.

Alignment (convergence) of color panels MT1050


I can assist you with that if you want. It is very tedious, but can be done. You need a cross hatch pattern generator or something with vertical and horizontal lines to lineup the LCD Panels again. Tricky little procedure if your not familiar with it. Let me know if i can assist you and hopefully save you agravation at the same time. Thanks Jay

Color guns out of alignment


It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
Have a great day!
