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.
SERVICE MODE 1
RASTER MODE
SUB 2 ADJ. MODE
Press the MENU button at the remote controller, it will enter into Service Mode Option.

OPTION
50Hz ADJ. MODE
SUB 1 ADJ. MODE
Press the MENU button again at the remote controller, it will jump back to Service Mode 1.
Press service/ language for 2 sec, it will enter into service mode 2.
Press service/ language for 2 sec again, it will jump back to service mode 1.

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.
• In the service option the user data establish as below,

Adjustment Condition / Procedure Waveform or others
1. Get the tuner ready to receive the CH. E-10 signal, but with no signal input. Adjust the PLL data.
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.

3. Call "RF-AGC" mode in service mode. Adjust the "RF-AGC" bus data to obtain the Tuner out­put pin drop 0.1 ~ 1.0 V below maximum volt­age.
4. Change the antenna input signal to 63 ~ 67 dBµV, and make sure there is no noise.
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.

1. Receive PAL Colour Bar signal. Signal content: 400 Hz 100% Mod.
2. Connect the probel of the meter (*) to (SI) con­nector.
3. Select the SUB-VOL in the service mode.

1. Receive the PAL Colour Bar signal.
2. Turn up the volume control to maximum, make sure the sound is heard from the speakers. Then put the unit in no signal state.
3. Check the sound mute is effective.
4. Finally turn sound level of CTV to minimum.

SIF(NICAM/IGR) ADJUSTMENT
Adjustment Condition / Procedure Waveform or others
1. Receive the PAL Colour Bar signal. (Set the receiving frequency at AFT OFF VHF high frequency.)
2. Connect the digital voltmeter to TP2300 or pin (1) of SC200 (in the main unit).
3. Verify that it is turned counterclockwise to 0V and clockwise to 5V , and adjust T2300 to make the DC voltage of TP2300 become 2.5 ± 0.1 V in the range.
* Single-unit adjustment
Vcc 5 ± 0.1V
IF input frequency 38.9MHz ± 10kHz. Control it under these conditions.
Adjust T2300 to make the DC voltage of TP2300 (in the NICAM unit) become 2.5 ± 0.1V.
After single-unit adjustment, check the practical setup.
Align the receiving frequency to the select chan­nel frequency. (AFT OFF)
The checked voltage must be2.5 ± 1.0V. (Take care that ± 1.0 is considered for the Vcc
difference between the single unit and unit, Fo difference and so on, but is not the adjustment precision.)

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.
* Every push of the monocolour key, changes the
screen as follows.

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
