Flicker, Shadows Or Dimness; Lamploc Not Working; Touch Panel Controller Is Blank; Blank Screen, No Display Of Image - Christie D4K2560 User Manual

A cross-connection hazard can occur when installing multiple projectors at once. A fire hazard
exists if a lamp power supply interlock cable is connected to a different projector than its lamp
power cables.

Flicker, shadows or dimness

• Make sure the shutter is fully open.
• Verify that a LampLOC calibration is not already in progress.
• Perform a LampLOC calibration.
• Increase the lamp power. Lamps which are near end of service may not operate reliably at a
lower power setting.

LampLOC not working

• If the Auto LampLOC option is not working, on the touch panel controller, tap Menu > Lamp
> LampLOC and adjust the lamp position manually. Observe screen brightness by adjusting
the X, Y and Z values or use a light meter to check for changes in brightness.
• Check that the flat part of the anode end of the lamp (if applicable) faces up in the anode yoke.

Touch panel controller is blank

• If the touch panel controller (TPC) display is blank, make sure the TPC communication harness
is connected securely.

Blank screen, no display of image

• Make sure both lens caps have been removed from the projection lens.
• Make sure the lamp is on.
• Make sure that all power connections are good.
• Make sure the shutter is fully open.
• Make sure that any test pattern (other than a full black test pattern or test pattern = none)
displays properly.

Cannot communicate with projector

• Make sure the computer and the projector are both connected to the network.
• Make sure that all input devices have the same subnet mask and unique IP addresses.
