Functional Tests

You perform the functional tests after you've repaired the projector to make sure all components of the
projector operate properly. You can also perform the functional tests if you're having trouble determining
what is wrong with the projector. For additional help in diagnosing trouble with the projector, see
Troubleshooting on page 60.

Notes
Make sure the video player has an S-video Out port and cables. The
player should also have a Composite video output port (RCA).
InFocus strongly suggests you use a DVD player to test the video
quality. DVD players reproduce colors better and project sharper
images. The least preferable is a VCR. If you must use a VCR, make
sure you use a commercially produced recording, not one recorded
from a broadcast source. The VCR must include an S-video connector
in addition to a composite connector.
You'll need the video in DVD, laser disc, or videocassette format.
InFocus strongly suggests you use Video Essentials, Optimizing Your
Audio/Video System (DVD International, 1997) available at

S-video, RCA composite, component video to S-Video adapter cable,
and RGB component with RGB to SCART adapter
HD15 VESA cable for analog video
3.5 mm mono audio cable
We recommend that you use test patterns you can download from the
InFocus web site to check image quality.

The computer must have a CD-ROM and a standard VESA connector
for analog output.
Ensure that the remote has fresh AA batteries.
Use a flat screen, not a curved one.
