7.2.4 Flicker, Shadows or Dimness

1. LampLOC™ may need re-adjustment.
2. LampLOC™ may be in the middle of its adjustment. Wait approximately 2 min.
3. Increase lamp power, if possible.
4. Determine if it is mid-level grayscale flicker (beating)-adjust 3-phase balancing for minimized ripple
(requires qualified service technician).
7.2.5 LampLOC™ Does Not Seem to Work
1. In the TPC Advanced Lamp menu, try adjusting lamp position using one button at a time-watch light
level for changes indicating lamp movement.
2. If the motors do not respond via any TPC buttons, you can position the lamp manually within the
projection head. UV danger. Qualified service technician only.
7.2.6 LiteLOC™ Does Not Seem to Work
1. Ensure LiteLOC™ is set and enabled in the Advanced: Lamp menu.
2. Changing the Lamp Power setting disables LiteLOC™.
3. If the lamp power has increased to its maximum in order to maintain a LiteLOC™ setting, LiteLOC™ is
automatically terminated. If the values shown in the Advanced: Lamp menu indicate that the lamp power
has reached this over-drive state, either reduce your LiteLOC™ setting or install a new lamp.

TPC

1. If the TPC fails to initialize, re-boot the projector and try again.
2. A failed TPC usually indicates a system failure requiring service.
3. A TPC communication failure (crash) while displaying a test pattern requires that the projector be cycled
OFF and ON again.
4. If the TPC response becomes sluggish, try re-booting the projector. If it persists, the installer may have set
the TPC Data Logging option to Detailed, which taxes memory and performance. For best results and
normal operation, this setting should be reduced to Errors or Standard.
5. Erratic TPC behavior or an error message such as "Could not write to file" can also indicate an
internal memory shortage. Make sure to regularly delete back-up files or corrupt files from the IPSM and/
or CompactFlash memory card. Save backups to a PC/laptop only, not the TPC (contact your administra-
tor).
6. If the locations of button presses on the screen seem to be misinterpreted, the TPC screen may need
recalibrating.
