Power Up with Top Case Removed
You can remove the top case and power up the projector to check fan or thermal switch operation. You
also do this to check internal voltages and signals, which may require additional projector disassembly.
Here's how to prepare the projector for power up with the top case removed.
1 Remove the top case (page 39)
NOTE The lamp must be in place and connected to start the projector with the top case removed.
2 Use vinyl electrical tape or other non-conductive means to hold the safety switch actuator in the
depressed (closed) position.
The projector can now be plugged into a power source and powered up.
CAUTION Once you plug in the power cord, take extreme care when touching the projector.
Check Controller ECA Voltages and Signals
1 Make sure the projector is unplugged.
2 Remove the power supply and AC filter ECA. (page 32)
3 Remove the chassis. (page 8)
4 Position the power supply and AC filter 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 two ECAs
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. Make sure to connect the AC filter ECA
to the power supply.
5 Connect the lamp to the lamp cable connector at the side of the lamp housing. Make sure the
connector fully engages the connector on the lamp module.
