If the image is flickering or unstable for a computer connection:
• Press the auto sync button on the projector or remote control.
• Press enter, go to Picture > VGA settings, and adjust Frequency or Tracking.
If the image disappears from the computer screen:
• For a notebook computer, you might be able to turn on both the external VGA port and
the built-in screen. Refer to the computer manual.
• Connect a monitor to the VGA-out port.
If text or lines from a computer display seem rough or uneven:
• Check the focus adjustment.
• Press enter, go to Setup > Reset keystone, and press enter.
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 Setup, and check that Mute is set to Not muted and Volume is correct.
• 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 55.
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.
