• Ensure the lens cap is not on either end of the lens.
• Ensure the lamp is ON.
• Confirm all power connections are OK.
• 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 cinema projector in the top, left corner.
• Ensure any test pattern other than the full black test pattern displays properly.

7.10 Severe Motion Artifacts
Verify if there is a synchronization problem with reversed 3-2 pull-down in the 60Hz-to-24Hz film-to digital
conversion and correct it at the source.
7.11 Image Appears Vertically Stretched or 'Squeezed' into Center of Screen
To regain full image width and proper proportions you may need to install an anamorphic lens. Open the
Source File Setup window and verify the resolution and aspect ratio settings. Open the Screen File Setup
window and verify the lens factor settings.
7.12 No Image, Just Pink Snow
This problem occurs when the correct cryptographic key is not available to decode encrypted cinema content..
• If the cinema projector security lid is unlocked or open, a warning appears on the Touch Panel Controller
(TPC). Pause or stop the show on the server and then close and lock the lid. Press Play on the server and wait
for the cinema projector to receive the decryption keys from the server. If the cinema projector does not
recover after 30 seconds, pause or stop the show and try pressing Play again. If this solution does not work,
reset the server. Check the Status window on the TPC for a tamper warning. If the lamp door is closed, the
tamper switch may be faulty.
• Ensure the IP octets for the cinema projector and the server match. Change if necessary.
• Tap Menu > Channel Setup. Tap Config 2 in the left pane and select LD Bypass.
