Remove and Replace the Chassis
The metal chassis (330-0963-xx) provides the necessary rigidity for the projector’s internal components
without adding much overall weight. The ballast/power supply ECA fastens to the chassis. The ground
spring (321-0218-xx) attaches to the chassis and provides ground continuity to the optical engine.
The ballast/power supply insulator (329-0433-xx) also fastens to the chassis. It provides electrical
insulation between the chassis and components on the ECA. Two retainer studs (340-1115-xx) fasten
the insulator to the chassis.
A new chassis does not include the ground spring, ballast/power supply insulator, or retainer studs.
If you're removing the chassis to access other FRUs in the projector, you don't need to remove the
ground spring or ballast/power supply insulator.
