Resolution
• Make sure the lens cover is removed from the lens.
• Make sure the lasers are armed.
• Make sure the douser is open.
• On the main TPC screen, tap
• Tap Menu > Channel Setup. Verify the correct channel is selected and the
settings are correct.
• Ensure an active source is connected properly. Check the cable connections and
make sure the alternative source is selected.
• Verify you can select test patterns. If you can, check your source connections
again.
• Verify that the input device is connected properly. If the input device is not
connected properly, the projector repeatedly attempts to display an image.
• The horizontal or vertical scan frequency of the input signal may be out of range
for the projector.
• The sync signal may be inadequate. Correct the source problem.
If you have resized the image, adjust the resizing settings until the entire image is
visible and centered.
Verify the quality of the signal from the input source.
Resolution
• If you have just turned on the projector, wait approximately five minutes for
the Laser Modules to warm up and the lasers to arm.
• Check the status of the interlocks. In the left pane, tap Menu > Status >
Interlocks. If the status is Critical or Unknown, press Manual Reset on the
projector to reset the interlocks.
• Check the status of the Laser Bank Manager. In the left pane, tap Menu >
Status > Laser Info. If the Laser Bank Manager Status in the right pane is
not Online, ensure the Rack Switch is on and an Ethernet cable is attached
from the Rack Switch to the TPC, to every Laser Module and to the Laser
Bank Manager. Check the status of the Laser Modules on the Laser Bank
Control Application.
