SAFETY INSTRUCTIONS

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE “X-RAY RADIATION PRECAUTION”, “SAFETY PRECAU-

TION” AND “PRODUCT SAFETY NOTICE” INSTRUCTIONS BELOW.

X-RAY RADIATION PRECAUTION

1. Excessive high voltage can produce potentially hazard­ous X-RAY RADIATION. To avoid such hazards, the high
voltage must not be above the specified limit. The nominal
value of the high voltage of this receiver is (A) kV at zero
beam current (minimum brightness) under a (C) V AC po wer
source. The high voltage must not, under any circum­stances, exceed (B) kV.

Refer to table-1 for high voltage (A), (B) & AC voltage (C).
(See SETTING & ADJUSTING DATA on page 33)

Each time a receiver requires servicing, the high voltage
should be checked following the HIGH VOLTAGE CHECK
procedure in this manual. It is recommended that the read­ing of the high voltage be recorded as a part of the service
record. It is important to use an accurate and reliable high
voltage meter.

SAFETY PRECAUTION

WARNING : Service should not be attempted by any one unfamiliar with the necessary precautions on this receiver . The following
are the necessary precautions to be observed before servicing this chassis.

1. An isolation transformer should be connected in the power line between the receiver and the AC line before any service is
performed on the receiver.

2. Always discharge the picture tube anode to the CRT conductive coating before handling the picture tube. The picture tube
is highly evacuated and if broken, glass fragments will be violently expelled. Use shatter proof goggles and keep picture tube
away from the unprotected body while handling.

3. When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in place, such as; non­metallic control knobs, insulating covers, shields, isolation resistor-capacitor network etc.

2. The only source of X-RAY RADIATION in this TV receiver
is the picture tube. For continued X-RAY RADIATION pro­tection, the replacement tube must be exactly the same
type tube as specified in the parts list.

3. Some part in this receiver have special safety-related char­acteristics for X-RAY RADIATION protection. For contin­ued safety, parts replacement should be undertaken only
after referring to the PRODUCT SAFETY NOTICE belo w.

GENERAL ADJUSTMENTS

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are
often passed unnoticed by a visual inspection and the protection afforded b y them cannot necessarily be obtained b y using
replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety char­acteristics are identified in this manual and its supplements; electrical components having such features are identified by
the international hazard symbols on the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement
parts which do not have the same safety characteristics as specified in the parts list may create shock, fire, X-ray
radiation or other hazards.

SERVICING PRECAUTIONS

■ Do not use a magnetized screw driver for screws
of Deflection Yoke 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.

2 ~ 5 mm

15 ~ 25 mm

■ 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.

■ Check the point of anode lead in a straight
line, if it is winding, please revise it.

RGB FOCUS ADJUSTMENT

1. Call-up the adjustment mode (see page 10)

2. Press a b utton on the remote controller in order to display
the internally-generated black cross-hatch (See TEST
SIGNAL SELECTION on page 11.)

3. Expose only RED by cover ing the GREEN and BLUE
lenses with caps.

4. Loosen the RED lens fixing screws (refer to Fig. a), and
adjust the RED lens focus to obtain the sharpest point
while observing the middle and peripheral sections of the
screen.

Fig. a

5. Use the focus VR of “R” of the focus pac k in order to adjust
the electric focus in the middle and peripheral sections of
the screen to its sharpest level.

6. Check the RED focus of the whole screen and if necessary
repeat steps 4 and 5.

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 black 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) If the horizontal line toward the right border 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.)

– 6 –

Note: The aim of the abov

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 war ming up time before the
adjustment is less than 30 minutes. (The horizontal line
in the screen middle section tends to be slightly red­flared.)

e-descr

ibed adjustment procedure

Note: Keep in mind that only the BLUE electric focus is ad-

justed with the black cross-hatch.

18. Check the BLUE focus of the whole screen and if neces­sary repeat steps 17 and 19.

19. Fix the BLUE lens by tightening its fixing screws.

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. Use the focus VR of “G” of the focus pack in order to ad­just the electric focus in the middle section of the screen
to its sharpest level.

Note: Nor mally the most clearly visible point of the scanning

line is the sharpest point of the Green focus, howev er as
the characteristics vary depending on the projection tube,
the sharpest focus points of the vertical and horizontal
lines may not match each other , thus when you turn the
focus VR, if the picture tends to be tremendously unstable
(rolls horizontally or vertically), adjust the balance of the
vertical and horizontal lines to its best position.

12. Check the GREEN focus of the whole screen and if
necessary repeat steps 10 and 11.

13. Fix the GREEN lens by tightening up its fixing screws.

14. Expose only BLUE by covering the RED and GREEN
lenses with caps.

15. Display the internally-generated black cross-hatch.

16. Loosen the BLUE lens fixing screws (refer to Fig. a), and
adjust the BLUE lens focus while observing the middle
and peripheral screen sections.

17. Use the focus VR of “B” of the f ocus pack in order to adjust
the focus in the middle section of the screen to its sharpest
level.
(The point of the Blue focus becomes sharpest when the
brightness level of BLUE is lowest, the cross-hatch is
clearly visible.)

TILT ADJUSTMENT

Rotate R, G, B deflection yoke so that picture becomes hori­zon, then fasten screw.

CENTERING ADJUSTMENT

1. Stretch a thread between two center of screen edge
(top and bottom, left and right).

2. Select the adjustment mode. (See page 10.)

3. Press TV/VIDEO button on the Remote Control to displa y
the black cross-hatch.

2. Case Study

In many cases, color matching problems can be solved by returning the HIT and WID data for main deflection to the
initial adjustment values. Convergence cannot be re-adjusted in the following cases.

2-1 When the CRT has been replaced

Main deflection re-adjustment and color matching are necessary when the CRT has been replaced. Use the following
procedure.

1. Replace the blue and red CRTs.

2. Perform the blue and red yoke horizontal adjustments in relation to the green CRT. Press the yokes and speed
modulation coils + alignments onto the CRTs and fasten after making sure that there are no gaps.

3. Adjust the blue and red alignments (refer to the detailed alignment adjustment item).

4. Use centering magnets to center the blue and red CRTs in relation to the green CRT.

5. Adjust the main deflection HIT and WID data, using the most accurate location in relation to the green as data.

6. Use convergence to match the colors for each screen. Green will not work at this time.

GENERAL ADJUSTMENTS

7. When the convergence adjustments have been completed for all screens, then replace the green CRT.

Repeat the procedures in steps 2 - 5 for the green CR T but this time use con vergence to match the colors using red and
blue as reference.

2-2 When replacing the convergence unit

Generally , all of the screens m ust be re-adjusted when the conv ergence unit is replaced, b ut the process can be greatly
shortened by using the following method.

1. Replace the memory (Q711, Q712, Q713) of the new unit with the memory (Q711, Q712, Q713) of the defective unit.
This makes it possible to quickly reproduce the previous screen status when installed in the set.

2. Install the new unit with the old memory in the set and turn on the power . The entire screen will move linearly in either
the vertical or horizontal direction.

3. Use centering magnets to re-adjust the green, red and blue centers.

4. There is possibility of color mismatching or differences in screen siz e when the various screens are check ed. In such
case, adjust the main deflection and apply a slight amount of convergence color matching.

2-3 When none of the above cases apply (rare case)

An unexpected situation or major operational error, etc., could be considered but it is recommended that all screens be
matched starting from the beginning. If the initial positions of the centering magnets are unknown, disconnect the
connectors for the convergence sub-yoke outputs one at a time, adjust the CRT centering and then start the following
adjustments.

1. Make sure that there is plenty of room for the static cross convergence to be moved left, right, up and down. If
sufficient space is not available, move to an appropriate location and then re-adjust the centering.

2. Enter the convergence adjustment mode and call out the menu. (Leave the PAL signal connected.)

3. Select 1. Adjust PAL Wide and adjust the PAL mode Wide/4:3 screen manually in accordance with the dimension

diagram.

4. When the Wide/4:3 screen adjustment has been completed, return to the Main Menu and select 2. PAL Wide to

others.

The screen will change automatically and the Wide, Cinema and Subtitle screens will be created automatically.

5. Next, select 3. Adjust PAL S.Live and mainly adjust in the horizontal direction in accordance with the dimension

diagram.

6. Next, select 4. Adjust PAL Cinema and fine adjust to remove any Cinema screen distortion.

7. Next, select 5. Adjust PAL Subtitle and fine adjust to remove any Subtitle screen distortion.

8. Next, select 7. PAL to NTSC (ALL), then calculate and copy the data for all PAL screens in the NTSC mode. At this

time, the calculations and screen shape changes will be performed automatically and the NTSC screen data
corresponding to the PAL screens will be transferred.

9. Select in sequence 8. Adjust NTSC Wide, 10. Adjust NTSC S.Live, 11. Adjust NTSC Cinema and 12. Adjust NTSC

Subtitle, check the respective NTSC screen modes and, if necessary, adjust for any distortion.
All of the screens can be adjusted with the above process but make every effort not to change the factory data unless

absolutely necessary. Try not to change the convergence data any more than necessary.
