Interruption problems

If the projector stops responding to all controls:

❏If possible, turn off the projector, then unplug the power cord and wait at least 15 seconds before reconnecting power.

If the lamp shuts off during a show:

❏A minor power surge might cause the lamp to shut off. This is normal. Wait a few minutes, then power on the projector.

❏If a red warning light is on or blinking, see “Warning light problems” on page 57.

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 due to glass fragments.

Remote control problems
