ADJUSTMENT PRECAUTIONS

SERVICE MODE

This model’s setting are adjusted in two different ways: though the I2C bus control and in the
conventional analog manner. The adjustments via the I2C bus control include preset-only items
and variable data.

1. Setting the service mode by the microprocessor.

1 Make a short-circuit JA373 and JA374, enter into the service mode. (Adjustment through

the I2C bus control). (Use JWS Key to set as well).

2 Press the CH DOWN / UP key on the remote controller to get ready to select the mode

one by one.

3 Press the CH DOWN / UP key on the remote controller to select the modes reversibly

one by one.

4 Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified.
5 When the short circuit between JA373 and JA374 is cut off, it will be released from the

service mode.

2. Factory Presetting.

1 Make a short-circuit JA373 and JA374 and turn on the main power switch. Initial values

are automatically preset, only when a new EEPROM is used (Judge with the first 4
bytes).

2 The initial data are preset as listed in page.

3

3 Make sure the data need modify or not (Initial data).

Note: Once the chassis has been assembly together and ready to be POWER ON for the

FIRST TIME, make sure to make a short-circuit JA373 and JA374 to switch to the
service mode position first and then turn on the main power switch. (See 2-1 above).

Precaution: If haven’t done this initiation, it may possibly generate excessive Beam
current.

1.) In the Service Mode, Key is used to select the mode in the following order.

User Data in Service Mode Option

• While SERVICE MODE 1 on, EEPROM DATA will switch to the service data.
Also, once press the menu button at the remote controller, EEPROM will switch
to SERVICE MODE OPTION.
Once press the menu button again at the remote controller, EEPROM will switch
back to SERVICE MODE 1.

2. Connect the sweep generator’s output cable
to the tuner antenna. (RF SWEEP)

3. Adjust the sweep generator’s to 80dBµV.

4. Connect the response lead (use LOW IMPED­ANCE probe with wave detector ; see Fig.1)
to the tuner’s IF output terminal. (This terminal
must have the probe alone connected).

5. Set the RF AGC to 0 - 6 V with no saturation
with the waveform.

6. Adjust the tuner IF coil to obtain the waveform
as shown in Fig. 2.

Note: Be sure to keep the tuner cover in position

during this adjustment.

1. Receive the PAL Colour bar signal.

5. Turn up the input signal to 90 ~ 95 dBµV to be
sure that there is no cross modulation beat.

1. Do not receive any signal.

2. Connect the digital voltmeter to TP803 (pin (54)
of IC800) in the main unit.

3. Call the "PIF VCO" Mode at the service mode.

4. Verify that it is turned counterclockwise to 0V
and adjust T800 to make DC voltage of TP803
become 2.5 ± 0.1 V in the range.

ADJUSTMENT

PURITY ADJUSTMENT

Adjustment Condition / Procedure Waveform or others

1. Select the green monocolour screen with re­mote controller, and set the beam current to

1.6mA with the contrast control.

2. Degauss the CRT enough with the degauss­ing coil.
Note: Follow the job instruction sheet to ad-

just the magnetic field.
*BH = 0
*Bv = refer to the job intructions sheet.

3. The purity magnet must be previously set at
the zero magnetic field and the convergence
must be roughly adjusted.
With P-Mag, adjust it to the center: rank A.

4. Observe the points a, b, as shown in Fig.4-1
through the microscope. Move DY fore and aft
to set the landing at the point (rank A).

5. If the a/b balance is poor, compensate it to the
center "Rank AB".

6. Align it to zero, keeping the raster rotation in
the east direction.

7. Tighten up the deflection coil screws.
Tightening torque : 180 ± 20N (18 ± 2Kgf)

8. Checking the CRT corner area, bond the mag­net sheet to set the landing at Rank A for com­pensation.
Note: Apply the adjustment after aging with the

beam current 1,600 ± 50µA or more for
30 minutes or more.

Note: Select the service mode, and press the

monocolour key of R/C for process, and
the monocolour screen (green) will be
selected.

UNIFORMITY ADJUSTMENT

Adjustment Condition / Procedure Waveform or others

Before adjustment begin, Horizontal magnetic
field=0G, Vertical magnetic field = 0.1G.
Make sure degauss it.

North Direction Red Uniformity

1. Horizontal mf = Set to monocolour screen Red
and adjust to +0.25G.

2. Pay attention to the edge of CRT, if the land­ing is poor, adjust by attaching the compensa­tion magnet at the back of CRT . Refer to Fig.5.

South Direction Red Uniformity

1. Horizontal mf = Set to monocolour screen Red
and adjust to -0.25G.

2. Pay attention to the edge of CRT, if the land­ing is poor, adjust by attaching the compensa­tion magnet at the back of CRT.

The same method is applied for adjustment of
monocolour screen Blue for blue uniformity, and
changing both the magnetic field for north and
south direction.

* During the pasting of compensation magent,

use the crosshatch pattern signal.
Make sure there is no blur or bend lines occur.
If the blur or bend lines are serious, adjust the
location of compensation magnet to make it
better.

Static Convergence Adjustment

1. Overlap blue and red with the open-/closing
angle and rotation of the 4 pole magnet.

2. Overlap green on blue and red with the open­/closing angle and rotation of the 6 pole mag­net.

Dynamic Convergence Adjustment

1. Fix the wedges in a position so that the de­flection yoke neck is at the center of top bot­tom and left right. (Straight line and without
any blur horizontal / vertical line)

2. Adjust the Red, Blue, upper and lower of the
center y axis on the screen by using the Vol­ume (YH,YHC) at the deflection yoke.
Refer to Fig. 6-2 and Fig. 6-3

3. If the Horizontal Red. Blue (XV) on the screen
center X axis is shifted, correct the Red. Blue
(XV) by adjusting the balance coil on the de­flection yoke.
Refer to Fig.6-4.

4. After confirm that there is no problems on the
entire screen, bond wedge on CRT and glass
tape on it. Fastening the screws of DY and
magnet unit (purity, 4-pole and 6 pole), then
coat the lacquer paint on DY fastening screw
and magnet unit fastening screw.

Note:In case of poor convergence adjustment
