Power Up With Top Case Removed To Check Fans And Voltages - Toshiba TDP-MT8 Service Manual

Power Up with Top Case Removed to Check Fans and Voltages

You can check the three fans and the lamp blower by removing only the top case from the projector.
Once the top case is removed, you can power up the projector and check internal voltages or verify
whether the fans operate.
1. Remove the following items:
Top case (see page 57)
Lamp blower contact ECA (see page 59)
NOTE The lamp and the lamp door must be in place to start the projector with the top case
removed.
2. Use black vinyl or other insulating tape to temporarily attach the lamp blower contact ECA to the
lamp module. The lamp blower must receive power for the projector to start. Ensure that the
contacts align properly.
3. Connect the lamp blower contact ECA cable to the controller ECA at J509.
4. Use a compatible remote control to power up the projector. To do this, point the remote at any
side of the projector and press Power.
If you do not have a remote, connect the keypad cable to the controller ECA and power up the
projector using the keypad.
CAUTION When you start the projector, there is voltage present on the controller ECA and power
supply. Be very careful where you probe and where you touch.
5. Do one or all of the following:
Check controller ECA voltages (see page 85)
Check the thermal switch (see page 91)
