temperature is more than 15°C above ambient, the projector assumes the coolant is not flowing and
the laser is turned off. This may happen if one of the following occurs:
Possible causes include:
• There is insufficient coolant volume in the liquid cooling system.
• The light engine DMD waterblock temperature sensor or harness (J83) is damaged or
improperly connected.
• The intake temperature sensor or harness (J82) is damaged or improperly connected.
• A quick disconnect in the cooling loop for the light engine is disconnected or not fully
connected.
Resolution
1. Check the coolant reservoir to ensure the coolant is between the minimum and maximum fill
lines.
2. Check all quick connect fittings on the radiator, light engine, and the liquid cooling reservoir.
Disconnect fully and reconnect until a click is confirmed.
3. Check for any kinks or leaks in the system.
4. Check to make sure the two temperature sensors have not failed or been disconnected.
LOS Dewpoint - Approaching Limit warning
Received a LOS Dewpoint - Approaching Limit warning during calibration.
Details
The projector is reacting to humidity to prevent damage in the laser optical subsystem (LOS). Due to
the laser power eventually being reduced, the brightness and color may be impacted.
Resolution
1. Operate the projector in a less humid environment.
2. If a new setup, the humidity levels inside the LOS may need 24 hours to normalize with the
environment.
For example, if the projector came from a hot, humid environment (outdoors, shipment) and
then brought into a cold, dry operating environment.
3. Increase the Maximum Expected Ambient setting in the LiteLOC
™
feature.
Received a LOS or laser driver board error
The projector displays a laser optical subsystem (LOS) or laser driver board error.
