Table 5-1. Troubleshooting Chart
Symptom Possible Cause(s) Solution
The projector does not turn on
after initial installation. • The Vision 10/12 is not
plugged in or the AC outlet
is not active.
• The remote control
batteries have run out.
• Ensure that the Vision
10/12 is plugged in and
that the AC outlet is active.
• Replace the batteries.
The projector is on, but there is
no video image on-screen. • Incorrect source selection.
• Source component is not
turned on.
• Select the correct source.
• Turn on the source
component.
A projected image from a DVD
is split or otherwise scrambled. • DVD player is set to
progressive scan mode. • Turn off progressive scan
on the DVD player.
• Connect the DVD player to
the HD/RGB 1 or HD/RGB 2
input.
Image is too bright and/or
lacks definition in the bright
areas of the image. • Contrast is set too high. • Lower the contrast setting.
Image appears “washed out”
and/or dark areas appear too
bright. • Brightness is set too high. • Lower the brightness
setting.
Colors in the image are
swapped; for example, reds
appear blue or vice versa. • The Red/Pr, Green/Y or
Blue/Pb outputs from the
source are connected to the
wrong inputs on the Vision
10/12. • Ensure that the source
outputs are connected to
the correct Vision 10/12
input.
RGB-HD images appear
“noisy.” • Clock and Phase settings
need adjustment. • Manually adjust Clock and
Phase settings, or perform
an Auto-Tune (refer to
HD/RGB Adjust on
page 42).
The projector will not turn
back on after it was powered
down, or the image disappears
during operation. • The projector will not turn
on for two minutes after
power-down, to protect the
lamp.
• The lamp has failed or was
improperly installed.
• Wait until the cooling fan
stops.
• Replace or re-install the
lamp.
