Assemblies.
1. Remove front and rear covers (Section 4.2).
2. Tilt the Electronic Module up and lock it in place (Section
3-3).
3. Remove the two pozidrive screws from the top of the High
Voltage Power Supply (HVPS) cover (Figure 4-5) and
loosen the one screw at the bottom of the cover (do not
remove the bottom screw-it is difficult to replace-the
HVPS will slide up and over it).
4. Remove the CRT anode cable (for the CRT that is to be
replaced) from the HVPS.
5. Disconnect the Yoke plug and cable harness from the
Scan Reversal PCB for the appropriate CRT (see Figure
3-7).
6. Remove the wires from the cable clamp for the CRT/Yoke
Assembly that is being removed.
7. Loosen the CRT Holder Ring (knurled knob in Figure 3-5).
NOTE: The CRT Holder Ring should be only hand-tight. If
it cannot be removed by hand only, a flathead screwdriver
can be used in the slots on the CRT Holder Ring to help
loosen it. Do not use a tool of any kind to tighten this ring-
it should be hand tight only.
