Printed Circuit Boards And Sensors; Replacing The Imxb Board; Replacing The Card Cage Convenience Light Boards (Clb) - Christie Crimson Series Service Manual

Printed circuit boards
and sensors
Printed circuit boards (PCB) mechanically support and electrically connect the projector components.
Sensors convert information such as temperature, light, and communication into electrical signals.
Always wear an electrostatic discharge (ESD) strap and use insulated tools when replacing circuit
boards.

Replacing the IMXB board

The IMXB module acts as the communication interface between the projector and the control systems.
1. Loosen the two captive screws and pull out the IMXB board.
2. Replace the IMXB board, if required.
3. To re-install, repeat these steps in reverse order.
Replacing the card cage convenience light
boards (CLB)
The card cage convenience light boards (CLB) provides extra illumination when needed for connecting
to the card cage.
1. Remove the electronics-side cover (on page 43).
2. Disconnect the one or two inline connectors, depending on which CLB is being removed.
The left CLB has one harness (J1) and the right CLB has two harnesses (J1 and J2).
3. Remove the two screws securing the CLB.
