Ballast Voltage Check Points - Toshiba TDP-P5 Service Manual

Ballast Voltage Check Points

To check the ballast input voltage, you need to remove the top case (see page 9). Leave the lamp
module installed in the projector. Then use the remote control or briefly short the power switch electrodes
to power up the projector.
Check to see if the ballast is receiving DC power from the power supply.
You can also check voltages on the controller ECA (see page 72) to see if it is receiving DC power from
the power supply.
