Sound problems If no sound is coming out of the projector: • Be sure you have an audio cable securely connected between the projector and the source device. • Press enter, go to Sound, and check that Mute is turned off and Volume is correct. • Press enter, go to Sound > Internal speakers, and be sure the speakers are turned on. • Press enter, go to Help > Diagnostics, and run the sound test. • Be sure that the mute and volume settings are correct on the source device, such as a VCR, camcorder, or computer. 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 59. 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 If the remote control does not operate: • Be sure nothing is blocking the remote control receiver on the front or back of the projector. Move to within 9 m (30 ft) of the projector. • Aim the remote control at the screen or at the front or back of the projector. • Move the remote control so it is more directly in front of or behind the projector and not as far to the side. • Press enter, go to Help > Diagnostics, and run the remote control test. • Replace the battery in the remote control.
