Remove And Replace The Controller Eca - Toshiba TDP-P5 Service Manual

Remove and Replace the Controller ECA

The controller ECA includes the controller and the formatter boards. The two boards fasten to each
other with three flexible ribbon cables. The formatter ECA plugs into a connector at rear of the optical
engine adjacent to the DMD. In addition to processing input signals from the remote control and keypad,
the controller provides all control functions and processes the data and video signals. A foam gasket on
the controller ECA provides airflow control to aid cooling inside the projector. The formatter ECA provides
final-stage signal processing required by the DMD.
If you need to remove the controller ECA to access a part beneath the board, see Partially Removing the
Controller ECA to Access Other Parts (see page 16).
NOTE A new controller ECA includes a foam gasket to control cooling airflow. Do not remove the gasket.
1 Remove the following items:
Lamp module (see page 7)
Top case (see page 9)
Controller ECA (partial removal - see page 16)
Optical engine (see page 26)
2 Gently pry the formatter ECA away from the optical engine until one side of the connector opens.
