1.
Try increasing the lamp power (TPC Advanced Lamp menu).
2.
The DMDs in the projection head may be overheated (this also triggers an alarm
window at the TPC).
3.
An interlock may be interrupting lamp function.
4.
Make sure the 220V connection near Panel C at the rear of the projector head (on
the underside) is still plugged in.
5.
Replace the lamp.
With this communication error, the lamp will be powered by the last lamp power
setting in effect.
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).
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.
1.
Make sure 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.
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 Compact Flash memory card. Save
backups to a PC/laptop only, not the TPC (contact your administrator).
6.
If the locations of button presses on the screen seem to be misinterpreted, the
TPC screen may need recalibrating.
