Section 4: Troubleshooting
4.3.5 LiteLOC™ Does Not Seem to Work
1. In the
Advanced Setup: Lamp Power/LiteLOC™ Setup
window, ensure LiteLOC™ is enabled.
2. 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 Setup: Lamp Power/LiteLOC™ Setup
window indicate that the lamp power has reached this “over-drive” state, either reduce your LiteLOC™
setting or install a new lamp.
4.4
TPC
1. If the TPC fails to initialize, re-boot the projector.
2. A failed TPC usually indicates a system failure requiring service.
3. If the TPC display is blank, touch the display screen to disable the screen saver. If the display screen is still
blank, ensure the TPC is on by opening the flap at the back of the TPC and verify the grey button in the
bottom left corner is ON. Also ensure that the connector is securely plugged into the back of the projector.
4. If the locations of button presses on the screen seem to be misinterpreted, the TPC screen may need
recalibrating. In the
Administrator Setup: Preferences
window, click the
Calibrate Screen
button and
follow the onscreen instructions.
4.5
Ethernet
4.5.1 Trouble Establishing Communication with Projector
Ensure Ethernet settings are valid for the site. All devices should have the same subnet mask yet unique IP
addresses.
4.6
Displays
Some of the following troubleshooting entries assume the use of a third-party input source for displaying
alternative “non-cinema” material. Before proceeding, ensure to consult the documentation supplied with the
external equipment.
4.6.1 Blank Screen, No Display of Cinema Image
1. Ensure the lens cap is not on either end of the lens.
2. Ensure the lamp is
ON
.
3. Confirm all power connections are still OK.
4. Ensure the douser is
OPEN
by verifying the state of the douser on
Main
panel as well as the state of the
douser switch at the back of the projector in the top, left corner.
5. Ensure any test pattern other than the full black test pattern displays properly.
6. Is the correct display file selected?
7. Is the correct cinema port connected for this display file (i.e., 292-A or 292-B)?
Check connections.
