SERVICING PRECAUTIONS
■Check the point of anode lead in a straight
line, if it is winding, please revise it.
Anode lead holder
■Do not use a magnetized screw driver for screws
of DeflectionYoke and Velocity Modulation Coil to
avoid magnetization of electron gun.
Magnetization of electron gun will degrade basic
function and result in unbalance of right and left
shift of user static convergence, and result in no
variable quantity.
■When replacing the anode cap assembly (CRT) or
anode lead assembly (F.B.T.), remove the anode
lead holder from old one and attach the holder
again to new anode lead.

2Centering magnet
After adjusting picture tilt, picture position is finally fixed
by this magnet.
Inorder to get maximum margin of user convergence con-
trol for center of screen, this magnet have to be used for
center convergence adjustment.
PREPARATION
Operate the receiver for at least 5 minutes.

4. Adjust the data of items RCUT,GCUT, and BCUT to
"40H".
5. Press the -/-- button on Remote. (Y-MUTE : ON)
6. Gradually rotate R, G and B screen volume of FOCUS
PAC clockwise or counterclockwise until the raster
appears slightly on the CRT through the each lens, and
leave them.

adjust the RED lens focus to obtain the sharpest point
while observing the middle and peripheral sections of the
screen.

7. Fix the RED lens by tightening its fixing screws.
8. Expose only GREEN by covering the RED and BLUE
lenses with caps.
9. Display the internally-generated cross-hatch signal.
10. Adjust the GREEN lens focus on the left border of the
screen to its sharpest level, then check the focus on the
right border, and if it is at its sharpest level, fix it in that
position by tightening the lens screws.
(1) If the horizontal line toward the right border is red-
flared, turn the lens screw slightly right in order to
balance it with the left border.(After adjustment, the
left border tends to be slightly green-flared, and the
right border tends to be slightly red-flared.)
(2) Ifthe horizontalline towardthe rightborder is green-
flared, turn the lens screw slightly left in order to
balance it with the left border.(After adjustment, the
left border tends to be slightly red-flared, and the
right border tends to be slightly green-flared.)
Note:The aim of the above-described adjustment procedure
for the Green lens focus is to obtain the best lens focus
after 2 - 3 hours of warming up taking into account the
focus drift; it applies if the warming up time before the
adjustment is less than 30 minutes. (The horizontal line
in the screen middle section tends to be slightly red-
flared.)

GENERAL ADJUSTMENTS
SPECIFIC INFORMATIONS
In case of warming up of more than 2 hours under a condition
that the large anode current is running through the projection
tube so that for example the all-white pattern appears, adjust
to obtain the sharpest focus while observing the whole screen
like in the RED case.
11. Press abuttononthe remote controllerinorder to display
the internally-generated black cross-hatch. (See TEST
SIGNAL SELECTION on page 11.)
12. Use the focus VR of “G” of the focus pack in order to ad-
just the electric focus in the middle section of the screen
to its sharpest level.
Note:Normally the most clearly visible point of the scanning
line is the sharpest point of the Green focus, however as
thecharacteristicsvary dependingon the projectiontube,
the sharpest focus points of the vertical and horizontal
lines may not match each other, thus when you turn the
focusVR, if thepicture tends tobe tremendouslyunstable
(rolls horizontally or vertically), adjust the balance of the
vertical and horizontal lines to its best position.
13. Check the GREEN focus of the whole screen and if
necessary repeat steps 10 and 11.
14. Fix the GREEN lens by tightening up its fixing screws.
15. Expose only BLUE by covering the RED and GREEN
lenses with caps.
16. Press abuttononthe remote controllerinorder to display
the internally-generated cross-hatch (See TEST SIGNAL
SELECTION on page 11.)
17. Loosen the BLUE lens fixing screws (refer to Fig. a), and
adjust the BLUE lens focus while observing the middle
and peripheral screen sections.

focus of each R, G, and B tube.
2. G adjustment
1) Set to the G monochrome by lens cap.
2) Receive the image of crosshatch.
3) Adjust the G electric focus.
Adjust the G electrical focus by the focus volume of focus block (Z410)
so that the screen center will come to optimum focus. (Although the G
electrical focus is to be adjusted to allow the scanning lines in the center
of the screen to be seen most clealy, if G alignment and astigmatism are
inferior with the appearance of vertical and horizontal flares in the center
of and around the screen and if the lines become thicker, adjust to the
best point observing the entire screen.)
4) Adjust the G lens focus. (Details on43PH and 42W are mentioned in the
next page)
Keep an eye on the center of the crosshatch pattern and adjust so that
the screen center will become clear.
As a rough guide to decrease unevenness, adjust so that red flares on
both sides of the crosshatch line will come to 1mm in thickness.
5) Repeat 4, 5, and attempt to further improve the focus quality.

adjustments on the G lens focus, and check that the focus balance on the
right and left is satisfactory.
(Balance check of left-and-right G lens focus)
(1)Adjust the G lens focus best by crosshatch of the left end (or the right end).
(2)Check the focus of the right end (orthe left end).
If the balance of the left and right lens focus (flare) is different, part it and
adjust to the medium quality.
Check the environment and confirm that the focus quality (including flare) is
within a tolerable range.

4) Receive the image of crosshatch pattern.
5) Adjust the B lens focus.
Pay attention to the border of the blue line and the black (background) in the vicin-
ity of the screen center.
First of all, make coarse adjustments of the lens, and move the lens adjusting
screw to the right at the point being considered as the best focus. Then, the lines
of the border become clear. Check and confirm under the circumstance that a
flare appears. On the contrary, if the lens adjusting screw is moved to the left from
the situation, the flare will disappear, and at this point you will find a point from
which the borderline itself begins to go out of focus. Adjust to the very point where
the focus begins to go out.
