Note on the remote commander
•The supplied remote commander is used on several models of

Notes
•When you turn on the TV, you may hear the “boon” sound
that is caused by the demagnetization of the TV. This does not

2Using a thumb press down, then pull up the rubber cap firmly in the direction indicated
by the arrow b.
3When 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.
•HOW TO HANDLE AN ANODE-CAP
1Do not damage the surface of anode-cap with sharp shaped objects.
2Do 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.
3Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage the rubber.
•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.

•These adjustments should be performed with rated power
supply voltage unless otherwise noted.
Controls and switch should be set as follows unless otherwise noted:
PICTURE control........................................................... normal
BRIGHTNESS control................................................... normal
Preparation :
•In order to reduce the influence of geomagnetism on the set's
picture tube, face it east or west.
•Switch on the power and degauss with the degausser.

1. Input a white signal with the pattern generator.
Contrast
Brightness
2. Set the pattern generator raster signal to green.
3. 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 3-1 through 3-3.)
4. Move the deflection yoke forward and adjust so that entire
screen is green. (See Figure 3-1.)
5. Switch the raster signal to blue, then to red and verify the
condition.
6. When the position of the deflection yoke has been decided,
fasten the deflection yoke with the screws.
7. If the beam does not land correctly in all the corners, use a
magnet to adjust it. (See Figure 3-4.)

•Operation of V.STAT magnet.
If the V.STAT magnet is moved in the direction of the aand
barrows, the red, green and blue dots move as shown below.
•Operation of BMC (Hexapole) magnet.
If the blue or red dot does not converge with the other two dots,
perform following steps.
Move BMC magnet (a) to correct insufficient H.static
convergence.
Rotate BMC magnet (b) to correct insufficient V.static
convergence.
In either case, repeat Beam Landing Adjustment.
1. (Moving vertically), adjust theV.STAT magnet so that the red,
green and blue dots are on top of each other at the center of the
screen.
2. (Moving horizontally), adjust the H.STAT VR so that the red,
green and blue dots are on top of each other at the center of the
screen.

If no acknowledgement is returned from a device which is turned "ON", the device has a problem.
In this case, one of the LED's responding to the problem device will flicker a defined number of times.
Flickering is operated by lighting the LED's for 60ms each time.

NOTE
• Note for Different Data Those are the standard data values written on the microprocessor.Therefore, the data values of
the modes are stored respectively in the memory.
In case of a device replacement, adjustment by rewriting the data value is necessary for some
items.
• 50..............50 Hz data
• 60..............60 Hz data
• Note for Different Data listed on the adjustment item table are reference values, therefore it is different for every model.
