There is no sound. What should I do?

• Try the following:
  • Press the button on the projector or remote control to turn up the volume.
  • If you've turned off the picture and sound, press the A/V Mute button on the remote control to turn them on again or open the A/V Mute slide.
  • If you're using a DVD player or other video source, make sure its volume is not turned all the way down or muted. Also, make sure the cables are connected correctly. See Connecting to Computers and Other Equipment.
  • Make sure the audio cable is connected to the correct audio port. See the following for details:
    • Playing Sound Through the Projector (if you're connecting the projector to a computer).
    • Playing Sound Through the Projector (if you're connecting the projector to equipment using a composite video, S-Video, component video, or RGB video connection).
  • If your presentation includes computer audio, make sure the volume control on your computer is not turned all the way down or muted. Make sure the audio cable is securely connected to both the projector and your computer. See Playing Sound Through the Projector.
  • The wrong source may be selected. Press the Source Search button on the projector or the Search button or one of the source buttons on the remote control.
  • Try adjusting the Volume setting in the Settings menu. See Customizing Projector Features.
  • Make sure you are using a “no resistance” audio cable.
