ANODE LEAD REMOVAL
CAUTION:
To prevent damage, the following procedure must be used when removing an
Anode Lead from the Flyback Transformer.
1) Push the Anode Lead down.
CRT REPLACEMENT
1. Removal of the CRT
Caution!
High voltage should be completely discharged prior to CRT removal.
Since the CRTs receive high voltage from the Flyback transformer, discharge
by shorting the open end of the respective high voltage cable to chassis ground.
Note:
Refer to Cabinet Disassembly when performing steps 1 through 4.
1.
Remove the Speaker Grille, Front Board, and Screen Assy.
2.
Remove the Back Board.
3.
Remove the Anode Lead Wire from the Flyback transformer. (Use the above procedure)
4.
Remove the PCB-CRT.
5.
Remove 4 hex-screws "a" retaining the Optical Unit. [Figure 5-1]
6.
Remove 4 screws "b" retaining the Lens.
Note: DO NOT loosen the RED screws.
Doing so will break the seal between the
C-Element and the # 6 Lens, causing leakage of the CRT Coolant.
7.
Remove 4 screws "c" retaining the CRT. [Figure 5-2]
8.
Remove the Deflection Yoke from the neck of the CRT. [Figure 5-7]
2) While holding the lead down rotate
the lead 90º counter clockwise.
3) Carefully remove the Anode Lead
from the Flyback Transformer.
