3–14 Removing and Replacing FRUs
3.2.3 Discharging the CRT
You must discharge the CRT before removing the following FRUs:
• Power supply module
• Video casting assembly
• CRT/chassis assembly
Discharging the CRT is a process that drains to ground any voltages
that remain in the CRT and in the extra-high tension (EHT) cable after
turning power off.
WARNING
The following steps expose you to the CRT anode, which may
store a high voltage.
Discharge the CRT as follows:
1. Remove the rear cover (Section 3.1.1).
2. Remove the top cover (Section 3.1.2).
3. Remove the CRT anode cable from the cable clamp (Figure 3–13).
