Performing Functional Tests
on the TDP-P4
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 76.

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).
Toshiba 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.
Toshiba strongly suggests you use Video Essentials, Optimizing Your
Audio/Video System (DVD International, 1997). This 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 Toshiba section of the InFocus
web site to check image quality.
For example, you can use a PowerPoint presentation with sound,
photographs, graphics and .avi files.
