Harnesses; Replacing The Mini-Sas Light Engine Harnesses - Christie Boxer 4K Series Service Manual

Harnesses

Harnesses can transmit signals or electrical power.
Before servicing, always carefully observe the original lead dress. Take extra precautions to secure all
harnessing properly, especially in the high voltage circuitry areas (such as lamp cables). Replace any
wire that appears to have damaged insulation.

Replacing the mini-SAS light engine harnesses

The mini-SAS harnesses move data from the light engine to the card cage.
Estimated replacement time: 23.0 minutes
1. Remove the light engine (on page 73).
2. Disconnect the red, green, and blue mini-SAS harnesses from the light engine.
3. Replace the mini-SAS harnesses.
4. Reconnect the mini-SAS harnesses.
Make sure the access and bends are identical to what was installed or the harnesses do not
route properly.
5. Pull the longer blue mini-SAS harness towards the rear of the projector to remove the slack
from the light engine area that may cause interference with the fan.
6. Route the mini-SAS harnesses so none of them interfere with the fan in the light engine area.
