Lamp Burst
1. The lamp may burst if it continues to be used despite the end of its life, or if it
receives a strong shock during use.
2. When one Lamp burst, projector shows warning message, then switch to single lamp
mode.
Sample：
3. LED indicator message
Sample：
4. Replace with reference to lamp replacement procedure.
To avoid burns, cool off for at least 60 minutes after turning off the power.
Provide adequate ventilation to avoid inhaling mercury vapor.
Be careful of glass fragments when removing the lamp.
5. Prepare a vacuum cleaner. Recommended: Brush head
Sample：

6. Clean glass fragments with a vacuum cleaner
7. Clean the red part over 20 to 30 seconds carefully in the figure.
8. Install a new lamp
9. Access the OSD menu and switch to dual lamp mode
10.Reset the replacement lamp usage time

Upper cover
１.Remove all screws on the back and bottom of the main unit
２.Slide the top cover backward and lift it up.
CAUTION: Do not break the front hook. There is a connection harness on the front
LED PCB and main board on the back side of the cover, and do not pull strongly.
Main PCB
Remove main board shield

13
The main board is vertically inserted in the BNC board and the relay PCB. Confirm that
the connector is securely connected when assembling.

PSU
Open the power supply cover, remove all the connectors (pay attention when assembling),
remove the PSU. CAUTION: Put the harness in the clamp when assembling

20
Partition plate
Remove the partition plate separating the PCB and the optical engine. (screw x3)
CAUTION: If you cannot assemble well, check the distribution of the left lamp.
Be careful not to bend or hit the connector of the DMD board when assembling.
It is recommended to record such as photographing the state before disconnection due
to complicated arrangement.
