8. Lamp and lamp house
8.3 Realignment of the lamp in its reflector
Why realigning the lamp ?
With longer run times, the light output of the lamp will decrease, which results in a lower light output on the screen. This light output
decrease can be compensated by readjusting the Z-position of the lamp.
WARNING: This procedure may only be performed by qualified technical service personnel.
