Fixing Problems

A minor power surge might cause the lamp to shut off. Wait a
few minutes, then power on the projector.
❏ If the lamp indicator is on or blinking, unplug the projector after
it cools down. Remove and reinstall the lamp module. If this does
not fix the problem, install a new lamp.
If the lamp burns out or makes a popping sound:
❏ If the lamp burns out and makes a popping sound, the projector
will not turn back on until the lamp module has been replaced.
❏ If the lamp breaks, contact HP about repairs that might be
required.
