“Tint” on page 18 and “Contrast” on page 18.
Problem: Lamp seems to be getting dimmer
•
The lamp begins to lose brightness when it has been in use for
a long time. Replace the lamp as described in “Replacing the
Projection Lamp” on page 27.
Problem: Lamp shuts off

A minor power surge may cause the lamp to shut off. Unplug

Make sure the vents are not blocked.
