Remove And Replace The Ballast/Power Supply - Toshiba TDP-P5 Service Manual

Remove and Replace the Ballast/Power Supply

The ballast attaches to top of the power supply with plastic retainer rivets on standoffs. Providing high
voltage to strike and operate the lamp through the lamp cable, the ballast receives primary power from
the power supply. The lamp control cable connects the ballast with the controller ECA. When the
controller ECA detects proper operation of all projector systems at startup, it sends a signal to the ballast
through the lamp control cable to strike the lamp.
The power supply includes the AC plug and provides low voltage to the controller ECA, the optical engine
and the fans.
1 Place the projector upside down on the work surface.
Remove the lamp module (see page 7).
Remove the top case (see page 9).
2 Unplug the lamp control cable, the power supply control cable and the controller ECA power
cable from their connectors on the controller ECA.
