Place the projector on a soft surface ( such as an anti-static mat ) when running the tests.
Connect the following the I/O panel on the projector.
1. Video player through Composite Video and S-video ports.
2. Audio sources through Audio ports (RCA) or 3.5mm mini-jack.
3. Personal computer through RGB cable.
Notes
Make sure the video player has an S-video Out port and cables.
The player should also have a Composite video 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 produces recoding,
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, etc. format.
1. RCA Pin jack cable for Composite video & audio.
2. S-video cable.
3. RGB cable that come with the projector.
4. 3.5mm mini-jack cable for PC audio.
Ensure that the remote has fresh AA batteries.
Use a flat screen, not a curved one.
The stereo audio card should have either a 3.5mm stereo audio
Jack or RCA left and right output ports. The PC must have a
CD-ROM and must have outputs for RGBHV, VESA, D-sub15pin.
