Table 5-1. Troubleshooting Chart
Symptom Possible Cause(s) Solution
The projector does not turn
on after initial installation. The
power LED on the front of the
DHD Controller lights red after
you press the power button. • The DHD Controller is
connected to the LS-10d
incorrectly or not at all.
• The LS-10d is not plugged
in or the AC outlet is not
active.
• Verify the HDMI cable
connection from the DHD
Controller to the LS-10d.
Do not use a DVI cable
for this connection.
• Ensure that the LS-10d is
plugged in and that the AC
outlet is active.
The projector and DHD Con-
troller are both 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.
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
DHD Controller.
• Ensure that the source
outputs are connected to
the correct DHD Controller
input.
Image geometry is incorrect. • Incorrect aspect ratio
selection.
• Select the aspect ratio that
best matches the source
image and screen size
(refer to Table 4-1).
The projector will not turn
back on after it was powered
down, or the image disap-
pears during operation. • The projector will not turn
on for two minutes after
power-down, to protect
the lamp.
• The lamp has failed.
• Wait two minutes until the
LED at the front of the
DHD Controller turns red.
• Replace the lamp.
