DISASSEMBLY INSTRUCTIONS
1.
HIGH-VOLTAGE CAP (ANODE CAP) REMOVAL
1-1. Cautions before Removing
Discharge the anode voltage
(1)
The anode voltage is not discharged completely from
the CRT of this unit even after the power is turned off.
Be sure to discharge the residual anode voltage before
removing the anode cap.
Do not use pliers
(2)
Do not use pliers, etc. to remove the anode cap. If you
used pliers and bent the hook to remove the cap, the spring
characteristics of the hook could be lost, and when
reinstalled, the cap would come off from the CRT anode
button easily, causing an accident.
Do not turn the anode cap
(3)
If the anode cap is turned in the direction of its
circumference, the hook is likely to come off.

Turn over the anode cap on the side where the hook
was released and pull out the cap in the direction
opposite to that on which the cap was pushed. (See
Figure 4)
Caution : Do not pull out the anode cap straight up.
: Do not pull the cap forcibly. After removing
the cap, check that the hook is not deformed.
1-2. Anode Cap Removal
Discharge the anode voltage. (See Figure 1)
(1)
Connect a flat-bladed screwdriver to the CRT GND via
an alligator clip.
(2)
Use a tester to check the end of the screwdriver and
ground of the TV for continuity.
(3)
Touch the hook with the end of the screwdriver.
Caution : Be careful not to damage the anode cap.
(4)
Turn over the anode cap.
Caution : Be careful not to damage the anode cap.
(5)
Push the anode cap with your thumb in the direction of
arrow
1 as shown in the figure, then lift the cap in the
direction of arrow
2 to release the hook on one side.
(See Figure 3)

ANODE CAP REINSTALLTION
Observe the cautions carefully so that no accident
occurs due to a defect in installing the anode cap and
so it does not come off.
2-1. Caution before Reinstalling
Never turn the anode cap after installing it
Never re-use the hook when it has been deformed
(1)
If the anode cap is turned after it is installed, it may
come off. Therefore, arrange the high-voltage cable
before attaching the anode cap. (See Figure 1-1)
(2)
If you have attached the anode cap before arranging
the high-voltage cable, arrange the cable carefully so
the cap does not turn.

2-2. Anode cap reinstallation
(1)
Use a clean cloth moistened slightly with alcohol to
clean the installation section. (See Figure 2)
Caution : Check that the installation section is free
from dust, foreign matter, etc.
(2)
Coat the anode cap installation circumference with an
appropriate amount of the specified silicone grease
(KS-650N). (See Figure 2)
Caution : Be careful that silicone grease does not
enter the anode button.
(3)
Eliminate twisting, etc. of the high-voltage cable and
arrange it so that no twisting occurs. (See Figure 3)
Caution : If the cable is not arranged correctly, the
anode cap could turn and cause an
installation defect.
