Resolution
• Verify the power cord is connected to the projector and the AC power supply
correctly.
• Verify the touch panel controller (TPC) is on and the LEDs on the input panel
are illuminated. If the TPC is off and there are no LEDS illuminated, verify the
AC outlet to which the projector is connected is working and the TPC is
connected to the projector. If the AC outlet is working and the TPC is connected
to the projector, contact Christie support.
• If the TPC is connected to the projector and the LEDs on the input panel are
illuminated, on the TPC, verify in the Operational Status region of the Main
panel does not indicate a PIB failure.
• Make sure the TPC is connected to the projector.
• If the TPC fails to initialize, make sure the compact flash on the left side is
installed correctly.
• If the TPC fails to initialize, restart the projector.
• If the location of button presses on the screen are not interpreted correctly, the
TPC screen may need recalibrating. Tap Menu > Administrator Setup >
Preferences. Tap Calibrate Screen and follow the on screen instructions.
Verify all input devices have the same subnet mask and gateway and unique IP
addresses.
• Check the touch panel controller (TPC) for error messages.
• If a failure with PIB communications exists, reseat the board.
• Check the Ethernet status LED on the rear of the TPC.
• Verify that the internal fans are operating.
• Look through the service panel and verify that the green LED is lit. This
indicates the LVPS is operating.
• Check all of the harness connections between LVPS and backplane. Pay
particular attention to the small, white connecter on the LVPS.
• Replace the LVPS.
• Check the interlocks. See
• In the left pane, tap Menu > Status >Temperatures. Verify if the DMD
temperatures are too high. If the temperatures are too high, turn the lasers off
and allow the cooling fans to cool the projector.
• Check the condition of the air filters and clean or replace them if they appear to
be dirty.
• Verify that all fans are operating.
• Ensure DMD coolant hoses are plugged in.
• Ensure coolant level is full.
