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 60ss each time.
The flickering frequency responding to each failed device is shown below.

Note on the remote commander
•The supplied remote commander is used on several models of
the TV. If you do not find instructions for some controls that
are on the remote commander, that means your TV does not
employ the features of those controls, e.g.
L
and SOUND
MODE.
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
indicate a malfunction.
•The picture color may become abnormal if you change the
direction of your TV. To obtain the normal picture color, press

on the TV to turn off the TV for five minutes and then turn
it on again.
•Design and specifications are subject to change without notice.
•All contents in the instruction manual are subject to change
without notice.
WARNING
Do not install the appliance in a confined space, such as
a bookcase or built-in cabinet.
If you have any problems, read this manual again and
check the countermeasure for each of the symptoms
listed below.
If the problem persists after trying the methods below,
contact your nearest authorized service center or dealer.

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.
•HOWTO 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.
3-1. BEAM LANDING
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.)

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,
