1. Introduction
• Maintaining a projector and keeping its environment clean is necessary in order to reduce the chance of system failures.
• Not maintaining the machines may have following consequences:
Overheating problems
Higher material wearing (fans, pump, electronic parts)

1. Introduction
Safety first!
2.Maintenance types and actions
Type A (1 month maintenance actions)
• Remove and clean all projector covers
• Clean all dust filters of the projector
• Check the surface of the lens output side for dust. (it is not needed to remove the lens from the projector). Only clean if necessary.
• Check the porthole (both sides) for dust.
Type A (1 month maintenance actions)
2.Maintenance types and actions
2.Maintenance types and actions
• Overview
• Removal & Cleaning of the lamp cover• Removal & Cleaning of the rear cover• Removal & Cleaning of the input cover• Removal & Cleaning of the lens cover• Removal & Cleaning of side cover• Removal & Cleaning of top cover
Type A (1 month maintenance actions)
2.Maintenance types and actions
Type B (3 months maintenance actions)
• Use a vacuum cleaner to clean the air vents/inlets of the projector
• Clean the cabinet for overall dust accumulation onprojector covers.
• Level verification of the liquid cooling circuit
3.Ventilations – Exhaust - Cooling
4.Dust Filters
• The Intake Air Filter • The LAD Filter (Laminar Airflow Device on the Light
Engine)• The Radiator Filter
4.Dust Filters
Filters have following functions:
• Preventing dust contamination• Keeping the air conducts clean and granting a clean
airflow
Not cleaning/replacing filters on a regular basis results in:
• Lower airflow• Overheating of the system• Sudden lamp off• Sudden system shut down• Dust contamination on the optical parts
5.Lamp change maintenance actions1. Check the UV blocker of the Lamp House for dust.
2. Check the Reflector of the Lamp compartment for dust.
3. Visual inspection of the lamp anode and cathode connectors of the Lamp compartment.
4. Check if all cables are still tightened.

UPDOWN
Preserve lamp life• Proper operating environment conditions will preserve
lamp life!
• Room temperature: Comfortable room temperature is usually
acceptable. Between 50°F and 95°F (10°C – 35°C).
• Room humidity (non condensing): 20% to 80%.
• External exhaust extraction: Use the “Lamp Brochure” to find the
proper air flow in CFM that is required:

Troubleshooting common issuesProjector does Not Power ON!
1. Check the wall circuit breaker to see if it’s ON.
2. Check the status of the LEDs on the rear corners of the projector.
3. Verify power by looking through the rear grill. LED’s should be blinking orange/green. This
indicates theLVPS has power.
6.Projectors troubleshooting
Troubleshooting common issuesLamp Does Not Ignite!
1. Verify lamp hours.
2. Check for interlock failures.
3. For Environment communication failures (Temperatures, Fans RPM), re-boot and try again.
4. If the Alarms field of the Status window shows a LampPower Supply (LPS) communication problem, re-boot theprojector and try turning the lamp ON again.
6.Projectors troubleshooting
2. Troubleshooting common issuesLamp Does Not Ignite!
5. Check for an alarm condition.
6. Check Temperatures. If a DMD temperature is too high, the lamp will not ignite. Cool the projector and try again.
7. Ensure there is proper ventilation, air filters are not blocked and liquid cooling reservoir has coolant and is circulating.
8. Listen for a “clicking” noise to indicate the LPS is attempting to strike the lamp. If the lamp does not ignite after the second attempt, check the power level of the lamp
6.Projectors troubleshooting
2. Troubleshooting common issuesFlicker, Shadows Or Dimness!
1. Ensure the douser is OPEN completely.
2. Lamp Light output calibration may need re-adjustment.
3. Check the lamp power to see if power is consistent or varying. Try to increase lamp power, if possible. Lamps which are near end of life may not operate reliably at lowest power range.
6.Projectors troubleshooting
2. Troubleshooting common issuesBlank Screen, No Display of
Cinema Image!
• TPC fails to initialize, re-boot the projector.
• Ensure the lens cap is not on either end of the lens.
• Ensure the lamp is ON.
• Confirm all power connections are still OK.
6.Projectors troubleshooting
Troubleshooting common issuesProjector communication failure
• Trouble Establishing Server Eth Communication with Projector
• No Image, Just Pink Snow
• No Image, Just Solid Black or Green Display
• A black screen occurs when the Link Decryptor is not processing video produces a fixed black screen when not processing 2D content and a green screen when not processing 3D content.
6.Projectors troubleshooting
Troubleshooting common issuesBlank Screen, No Display of
Cinema Image!
• Ensure the douser is OPEN by verifying the state of the douser on Main panel as well as the state of the
• Ensure any test pattern other than the full black test pattern displays properly.
• Is the correct format file selected?
• Is the correct cinema port connected for this format channel (i.e., 292-A or 292-B/dual link)? Check Video connections.
