Fixing problems

❏If the internal DVD player is playing a DVD with DTS sound, press DVD menu and turn off the DTS sound and turn on stereo or Dolby sound. DTS sound plays only on a DTS-compatible sound system connected to the projector’s digital audio output.

❏Press menu, 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.

If no sound is coming out of an external sound system:

❏If you are playing an external source, be sure you have an audio cable securely connected between the source device and the sound system. The digital audio output from the projector functions only while playing the internal DVD player.

❏If you are playing the internal DVD player, be sure you have a correct cable connecting the projector to the sound system—either a digital audio cable connected between digital audio ports, or a standard audio cable connecting stereo audio ports.

❏Press menu, go to Sound, and check that Mute is turned off. The volume control does not affect the digital audio output and the stereo audio output.

❏If the internal DVD player is playing a DVD with DTS sound, press DVD menu and turn off the DTS sound and turn on stereo or Dolby sound. DTS sound plays only on a DTS-compatible sound system connected to the projector’s digital audio output.

❏Press menu, go to Sound > Internal speakers, and turn off the speakers

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.

❏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.
