70 Solving Problems
The colors of the image are not right.
■ If you’re displaying a computer image, use the Color Mode
option in the projector’s Video menu to adjust the color. If you’re
displaying video, adjust the
Color and Tint settings on the Video
menu. See page 40 for instructions.
■ Adjust the Brightness and Contrast settings on the Video menu.
■ Try adjusting the Color Temp setting on the Advanced menu.
■ If the images appear too green or too purple, check that the Input
Signal
setting is correct on the Video menu.
■ Check your computer display settings to correct the color balance.
■ The lamp may be nearing time for replacement. Check the lamp
hours as described on page 48 and replace it, if necessary, as
described on page 55.
There is no sound.
■ Try turning up the volume (see page 42).
■ If you’re using a VCR 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, as described in Chapter 1.
■ 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’s headphone jack or
audio out jack. See page 14 (for laptops) or Appendix A (for
other systems).
■ Make sure the Windows volume controls on your computer are
not turned all the way down or set to Mute. Check this by
clicking the volume control in your Windows System Tray (lower
right corner of the screen).
■ Make sure the A/V Mute button is not enabled.
■ The wrong source may be selected. Press the Source button on
the projector—or the
Computer or S-Video/Video button on
the remote control—to select the correct source.
