Functional Tests; Required Equipment - InFocus LP630 Service Manual

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 70.

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 video cassette format.
InFocus strongly suggests you use Video Essentials, Optimizing
Your Audio/Video System (DVD International, 1997). This DVD is
available at Amazon.com.
Use the cables that come with the projector, including the Digital
Video Interface (DVI) cable.
Use the Test Patterns available at the InFocus website to check
image quality.
For example, you can use a PowerPoint presentation with sound,
photographs, graphics and .avi files.
Ensure that the remote has fresh AA batteries.
Use a flat screen, not a curved one.
Make sure the card has an M1 Digital Video Interface (DVI) output
port. The stereo audio card should have either a 3.5mm stereo
audio jack or RCA left and right output ports. The computer must
have a CD-ROM and must have outputs for RGBHV, VESA, M1
Analog and M1 Digital.
Small self-powered speakers will work well.
