Flicker, Shadows, Or Dimness

LampLOC™ Not Working
• If the Do Auto option is not working, tap Menu > Advanced Setup >
LampLOC™ Setup and adjust the lamp position manually. Observe
screen brightness by adjusting the XYZ values or use a light meter to
check for changes in brightness.
• Check that the anode yoke (lamp yoke) is in the correct position. (Figure

• Check that the flat part of the anode end of the lamp (if applicable) faces
up in the anode yoke. For CDXL-20 and CDXL-30 lamps, the flat part of
the anode end of the lamp should be positioned at the 2 or 10 o'clock
position.
8.6
LiteLOC™ Not Working
• Tap Menu > Advanced Setup > LampPower/LiteLOC™ Setup. Tap
Enable LiteLOC
• If the lamp power is at the maximum setting to maintain a LiteLOC™
setting, LiteLOC™ is automatically disabled. Reduce the LiteLOC™ setting, or install a new lamp.
