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, refer to
Troubleshooting.
Below is the list of equipment you need for the functional tests. Following that is the list of tests you need
to complete.
Required Equipment
Equipment Notes
Video player
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 or laser disc player to test
the video quality. DVD and laser disc players reproduce colors better
and project sharper images. The least preferable is a VCR. If you 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.
Commercially produced video You'll need the video in DVD, laser disc, or video cassette format.
Audio cable Use the stereo audio cable that comes with the projector.
Audio adapter
Required if the audio source has RCA left and right output ports. Not
required if the audio source has a 3.5 mm stereo audio jack.
RGB test screens
Use the test patterns to check image quality. (Test patterns are
available at the ASC Resource Center at
www.infocus.com/service/asp/index
PC multimedia presentation
For example, you can use a PowerPoint presentation with sound,
photographs, graphics and .avi files.
Executive Plus remote control Ensure that the remote has fresh AAA batteries.
