2. "TV. UNIT" REMOVAL
2-1. Anode cap disassembly
2-1-1. Notice Before Disassembly
Discharge the anode.
1) The cathode-ray tube of this equipment has the structure
that the anode potential is automatically discharged
when the power is off. But immediately after the POWER
is turned off, there might be the case that the anode
potential has not been discharged completely. When
removing the Anode Cap, make sure to discharge the
anode potential.
Do not use a plier.
2) When using a plier to catch or loose the hook, the spring
is deteriorated depending on the gripping power of the
plier. Therefore, do not use a plier because the hook
may easily slip off from the CRT anode button and it will
be cause of accidents.
Do not rotate the Anode cap.
3) Do not rotate the Anode Cap. If the Anode Cap is
rotated, the hook may easily slip off.
2-1-2. Disassembly
Discharge the anode (See Fig-3).
1) Connect a flat-head screwdriver to the CRT GND using
a cable with clips.
2) Confirm that the electric current is conducted using the
tester at the tip of the screwdriver and the GND on the
TV side.
3) Put the tip of the screwdriver to the shutter hook.
Note) Take care not to scratch the Anode Cap.
4) Turn over the Anode Cap (See Fig-4).
Note) Take care not to damage the Anode Cap.
5) While pushing the Anode Cap in the direction of arrow
with the thumb as the left figure, lift it up in the direction
of arrow
and remove one side of the hook (See Fig-
5).
6) After the side is removed from the Anode Button, turn
over the edge of the Anode Cap, and pull it to remove in
the direction of the arrow (See Fig-6).
Note) Do not remove the Anode Cap in the direction of 90°
degrees (vertical).
Note) Do not pull it forcefully. Check that the hook has not
changed the shape after removing.
