Functional Tests - Toshiba TDP-S3 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 74.

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).
Use the cables that come with the projector, including the Digital
Video Interface (DVI) cable.
M1-A and M1-DA cables for both analog and digital playback.
We recommend that you use the Test Patterns available on the
Toshiba website to check image quality.
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 a standard VESA connector for analog output.
Ensure that the remote has fresh AA batteries.
Use a flat screen, not a curved one.
