REMOVAL OF ANODE-CAP
NOTE : After removing the anode, short circuit the anode of the picture tube and
the anode cap to the metal chassis, CRT shield or carbon paint on the
CRT.
REMOVING PROCEDURES
1
Do not damage the surface of anode-caps with sharp shaped objects.
2
Do not press the rubber too hard so as not to damage the inside of anode-cap.
A metal fitting called the shatter-hook terminal is built into the rubber.
3
Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage the rubber.
HOW TO HANDLE AN ANODE-CAP
3
When one side of the rubber cap is separated from the anode button,  the anode-cap
can be removed by turning up the rubber cap and pulling it up in the direction of the
arrow 
c
.

SECTION 3
ADVANCE OPERATION
3-1. "RESET" FUNCTION
1. Purpose
If a customer faces some setting problem that cannot be solved, using the "RESET" function some items will be
reset to its original setting (shipment condition)
2. How to Operate
The way to access to the "RESET" Function:-
a) By pressing "MENU" button or "SELECT" button (for non-menu models) on the Front Key Input and
hold it down for 5 seconds.
3. Subsequent of Operation
Sequential to the resetting operation (either methods being used in No. 2), TV set would shut down once and
automatically turn on again. The power-off duration is expected to be about 500msec. An OSD message,
"RESET" tentatively will be displayed for 10 sec after IK status gets stable.
As a result, some items will be reset to an initial condition (shipment condition) wheareas some other remains at
the last selection by user.

realignment is required or a new picture tube is installed.
These adjustments should be performed with rated power
supply voltage unless otherwise noted.
Controls and switches should be set as follows unless otherwise noted:
PICTURE control ...........................................................  normal
BRIGHTNESS control ...................................................  normal
Perform the adjustments in the following order :
1. Beam Landing
2. Convergence
3. Focus
4. White Balance
Note :  Test Equipment Required.
1. Pattern Generator
2. Degausser
3. Oscilloscope
SECTION 4

normal
Preparation :
In order to reduce the influence of geomagnetism on the set's
picture tube, face it east or west.
Switch on the set's power and degauss with the degausser.
4-1. BEAM LANDING
1. Input a white signal with the pattern generator.
Contrast
Brightness
2. Position neck assy as shown in Fig4-2.
3. Set the pattern generator raster signal to a green raster.
4. Move the deflection yoke to the rear and adjust with the
purity control so that the green is at the center and the blue
and the red take up equally sized areas on each side.
(See Figures 4-1 through 4-4.)
5. Move the deflection yoke forward and adjust so that the
entire screen is green. (See Figure 4-2.)
6. Switch the raster signal to blue, then to red and verify the
condition.
7. When the position of the deflection yoke has been decided,
fasten the deflection yoke with the screws and DY spacers.
8. If the beam does not land correctly in all the corners, use a
magnet to adjust it.
(See Figure 4-5.)
