I picked up a Barco 701s while I am between digital projectors, after doing a lot of reading and with a considerable amount of help and enthusiam from a fellow forum member TheRitz we have it showing a pretty good image from my pc. However the blue lens, just cannot focus as sharply as the green and red lens. Any suggestions as to the problem or solution? The projector is in fairly good condition, very clean inside, a few small scratchs on the lens, all the functions and menus work well and the menu shows some 3320 hours use. I have to admit to taking great pleasure from going through the service and installation menus and only hope that this is just scratching the surface of the tweakability of the machine. Heres hoping that the blue lens focus is something small!.... thx. Vex.
