Check Controller Voltages
To check voltages, you need to power up the projector with the top case removed. See page 80 for
instructions on how to do this.
Check Controller ECA Voltages and Signals
1. Prepare to power up the projector with the top case removed. (page 80)
2. Remove the chassis. (page 12)
3. Position the ballast/power supply ECA near enough to the projector to connect the
controller/power supply cable from the controller ECA. You can do this if you turn the
ballast/power supply ECA over and connect it to the controller ECA in an upside-down position.
This also leaves you room to access the controller ECA with measurement probes.
4. Connect the lamp to the lamp cable connector at the side of the lamphouse. Make sure the
connector fully engages the connector on the lamp module.
