Removing and Replacing FRUs
This chapter describes how to remove and replace the VR320 monitor field
replaceable units (FRUs).
3.1 Procedures
Perform all the removal and replacement procedures from the rear of the
monitor. Tilt the monitor from the back to the front allowing easier access
to the FRUs.
NOTE
If you twist the monitor while applying the tilt pressure, the
monitor moves easily.
The procedures describe how to remove FRUs. To install each FRU,
reverse the removal procedure. Before removing any FRUs, you must
remove the rear cover and the top cover.
WARNING
Turn power to the monitor off and remove the power cord before
disconnecting or replacing any FRU.
NOTE
Any time you replace a video casting assembly, deflection module,
or power supply module, perform all the necessary adjustments.
