The projector does not turn
on or respond to user com-
mands. The vacuum fluores-
cent display on the Primary
DHD Controller front panel
displays the following mes-
sage:
Primary Display Error
Communication Failure
• The serial connection from
the Primary DHD
Controller to the display is
incorrect or the cable is
faulty.
• Ensure that the
Display Control (RS-232)
output from the Primary
DHD Controller is properly
connected to the display
(see Figure 3-11).
The Secondary DHD Control-
ler does not turn on or
respond to user commands.
The vacuum fluorescent dis-
play on the Primary DHD
Controller front panel dis-
plays the following message:
Secondary DHD Error
Communication Failure
• The serial connection from
the Primary DHD
Controller to the
Secondary DHD Controller
is incorrect or the cable is
faulty.
• Ensure that the RS-232
(To Accessory Box)
connectors on the Primary
and Secondary DHD
Controllers are connected
to each other, using a
known-good,
“null-modem” (cross-over)
cable (see Figure 3-12).
The 3Dimension Processor
does not turn on or respond
to user commands. The vac-
uum fluorescent display on
the Primary DHD Controller
front panel displays the fol-
lowing message:
BAE Error
Communication Failure
• The HDMI CEC
connection from the
Primary DHD Controller to
the 3Dimension Processor
is incorrect or the cable is
faulty.
• Ensure that the HDMI 1
input on the Primary DHD
Controller is connected to
the Left HDMI output on
the 3Dimension
Processor, using a
known-good HDMI cable
(see Figure 3-12).
When displaying 3D content,
crosstalk or “ghosting” can be
seen — that is, the left eye is
perceiving some of what the
right eye should be seeing or
vice versa.
• Primary and Secondary
images are not properly
aligned.
• Rear-projection installation
uses second-surface
mirrors that are producing
faint, secondary
reflections.
• Refer to Power-Up
Sequence and Optical
Alignment Procedure on
page 49.
• Always use first-surface
mirrors in your
rear-projection installation.
With 3D glasses, image per-
spective is reversed — that is,
“left-eye“ frames appear in the
right lens and vice versa.
• Incorrect Reverse Eyes
setting.
• Change the
ReverseEyes setting
(refer to Reverse Eyes on
page 75).
