Projector boots up and becomes unresponsive
with v1.2.0 software
A defect in the v1.2.0 software can prevent the D4K-60 projector from properly booting. If the
defect occurs, after applying AC power the projector starts to boot, reaches standby, and becomes
unresponsive.
Details
The defect is caused when the lamp power supply (LPS) initializes faster than expected. For more
details, see the
D4K Software v1.2.1 Upgrade Information Bulletin (P/N:
Solution
Check the following:
•
This only happens on AC start as opposed to the projector failing after it has been on for more
than five minutes, an hour, or a day.
•
Disconnecting and reconnecting the TPC does not fix the Connection Lost message.
•
Power cycling the projector does not solve the problem.
•
The user cannot connect using the web page.
•
Serial commands using Ethernet/RS232/RS422 do not work.
If the above solutions do not work, contact Christie Technical Support.
Shutter out of sync
The shutter indicates the wrong status, for example it shows open on the status report but is
closed.
Details
The Shutter SW and HW statuses are not in sync, causing the projector to indicate the wrong
status.
Solution
Use the SHU serial API command to ensure the Shutter SW and HW states are in sync. Only issue
the control commands when the projector is in the Standby or Power On states. Do not issue the
commands when the projector is in the Lamp On state.
1. To synchronize and open the shutter, issue the Close and then Open serial API commands.
The shutter is now in sync.
2. To synchronize and close the shutter, issue the Open and then Close serial API commands.
