Functional Tests; Required Equipment - InFocus DP8000 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 72.

Required equipment

Equipment Test
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). PROXIMA 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.
Commercially You'll need the video in DVD, laser disc, or video cassette format. PROXIMA strongly
produced video suggests you use Video Essentials, Optimizing Your Audio/Video System (DVD
International, 1997).
Audio & Video Use the cables that come with the projector, including the Digital Video Interface
cables (DVI) cable.
RGB test screens Use the Test Patterns on the InFocus website to check image quality.
External amplified
speakers
PC multimedia For example, you can use a PowerPoint presentation with sound, photographs,
presentation graphics and .avi files.
Remote control Ensure that the remote has fresh AA batteries.
Projection screen Use a flat screen, not a curved one.
PC with digital Make sure the card has an M1 Digital Video Interface (DVI) output port. The stereo
video and sound audio card should have either a 3.5mm stereo audio jack or RCA left and right output
card ports. The computer must have a CD-ROM and must have outputs for RGBHV,
VESA, M1 Analog and M1 Digital.
