Troubleshooting suggestions 63
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.
