All the mirrors can be aligned, however only the mirrors
mentioned below should be aligned. To place a mirror in it’s
nominal position, put a 2mm wide spacer between the mirror
and the lighthouse, and then fix the mirror.
8.1
Integrator 1
Put on a white picture. If dark bars are visible on the edges,
then integrator 1 has to be aligned. Unscrew the 2 screws (A)
on top of integrator 1, and the integrator can be moved
left-right. Align for minimal dark bars, and if possible align for
middle position between dark edges. If dark edges are visible
in the top or bottom, adding or removing small filling plates
below the bracket fixing the integrator can align this.
8.2
Mirror B
Put on a green picture. If dark bands are visible on the sides,
loosen the two screws (B) fixing the mirror on top, and move
the mirror till the dark bands are gone.
8.3
Mirror C
Put on a red picture. If dark bands are visible on the sides,
loosen the two screws (C) fixing the mirror on top, and move
the mirror till the dark bands are gone.
8.4
Mirror D1
Put on a blue picture. If dark bands are visible on the sides,
loosen the two screws (D) fixing the mirror on top, and move
the mirror till the dark bands are gone.
8.5
Lens 3 green assy (polarizer green)
Put on a black picture. Loosen the screw (E) on top.
Move the screw for minimal green in the picture.
8.6
Lens 3 red assy (polarizer red)
Put on a black picture. Loosen the screw (F) on top.
Move the screw for minimal red in the picture.
8.7
Lens 6 blue assy (polarizer blue)
Put on a black picture. Loosen the screw (G) on top.
Move the screw for minimal blue in the picture.
8.8
Convergence alignment
Remove the drive board. If the set is now switched on the
picture will be fully white. Any convergence error will show up
as a coloured band at one side of the picture.
The convergence should be aligned in such a way that the
coloured bands are minimal.
Please note the projector will only work for a few minutes in
this position. If the projector switches off, remove the mains,
plug it back in, and the projector will work again. Putting the
projector is service mode will stop it from switching off.
To align the convergence loosen the two torkx screws (H) at
the top of the LCD-holding plate so, that you can move the
holding plate with the LCD freely, but not easily. Now grab the
top of the holding plate (J) with the fingers of 2 hands. Move
the plate with the LCD till the convergence is optimal (no
coloured band on the side). This is easiest by first getting the
picture straight, then moving the picture left right and then
moving the picture up/down.
Always align convergence of red and blue with respect to
green.
