IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only.
SERVICE OF HIGH VOLTAGE SYSTEM AND PIC- TURE TUBE When servicing the high voltage system, remove static charge from it by Connecting a 10K ohm Resistor in series with an insulated wire(such as a test probe) between picture tube dag and 2nd anode lead. (AC line cord should be disconnected from AC outlet.)
1. Picture tube in this receiver employs integral implosion protection. 2. Replace with tube of the same type number for continued safety. 3. Do not lift picture tube by the neck. 4. Handle the picture tube only when wearing shatterproof goggles and after discharging
the high voltage completely.
X-RAY This receiver is designed so that any X-Ray radiation is kept to an absolute Minimum. Since certain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range, the followin precautions should be observed: 1. When repairing the circuit, be sure not to increase the high voltage to more than 33.0kV
(at beam 0 µA) for the set.
2. To keep the set in a normal operation , be sure to make it function on 30.0kV ±1.5kV (at
beam 1,700 µA) in the case of the set. The set has been factory - Adjusted to the above-
mentioned high voltage.
∴∴ ∴∴
∴If there is a possibility that the high voltage fluctuates as a result of the repairs,
never forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorized types and/or brands which may cause
excess X-ray radiation.
BEFORE RETURNING THE RECEIVER Before returning the receiver to the user, perform the following safety Checks. 1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not
lodged between the chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers,
cabinet backs, adjustment and compartment covers or shields, isolation resistor- ca- pacity networks, mechanical insulators etc.

ADJUSTMENT PRECAUTIONS
This model’s setting are adjusted in two different ways: through 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.
1When the JA366 and JA367 are short-circuited, enter into the service mode.
(Adjustment through the I2C bus control).
(Use JWS Key to set as well).
2Press the CH DOWN / UP key on the remote controller to get ready to select the
mode one by one.
3Press the CH DOWN / UP key on the remote controller to select the modes
reversibly one by one.
4Using the VOLUME UP/ DOWN key on the remote controller, the data can be modi-
fied.
5When the short circuit between the JA366 and JA367 is cut off, it will be released
from the service mode.
2. Factory Presetting.
1Short JA366 & JA367 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).
2The initial data are preset as listed in page 5 to 8. 3Make sure whether the data need to modification 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 short JA366 & JA367 to switch to the service mode position first and then turn on the main power switch. (See 2-11
11
1above).
Precaution: If haven’t done this initialization, it may possibly generate excessive Beam current.

11. Get the tuner ready to receive the CH. E -9
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 IMPED-
ANCE 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.
RF-AGC TAKE OVER POINT AD- JUSTMENT (I2C BUS
CONTROL)
1. Receive "PAL COLOUR BAR" signal.
»Signal Strength: 54 ±1 dBµV (75 ohm open)
2. Connect the oscilloscope to TP51 (Tuner’s AGC
Terminal) as shown in Fig. 3.
3. Call "RF-AGC" mode in service mode. Adjust the
"RF-AGC" bus data to obtain the Tuner output pin drop 0.1V ~ 1.0V below maximum voltage.
4. Change the antenna input signal to 63~67dBµV,
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.
Note: For the 50 W signal
strength gauge, when not us- ing 50/75 impedance adapter, signal strength is 52±1dBµV(75 W open), in-
stead of 54±1dBµV (75 W
open).
Precaution: The loss of using
impedance adapter.

PURITY ADJ. 1. Select the green monocolour screen with re-
mote controller, and set the beam current of 1.7mA with the contrast control.
2. Degauss the CRT enough with the degausing coil.
For the adjustable magnetic field
NOTE: Horizontal = 0
Vertical = 0.1
Adjustable magnetic field is shown in P8-1.
3. The purity magnet must be previously set at the
zero magnetic field, and the convergence must be adjusted to be rough. With P-MG, 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. Aline it to zero, keeping the raster rotation in the
east direction.
7. Tighten the deflection coil fastening screws.
»Tightening torque: 108 ±20 N (11 ±2 kgf)
8. Checking the CRT corner area, bond the mag-
netic sheet to set the landing at Rank A for com- pensation.

Uniformity adjustment (To perform after the purity and convergence adjustment.)
2Before adjustment begin,
Horizontal magnetic field = 0G Vertical magnetic field = Each destination's adjust- ment magnetic field. 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 mag- net at the back of the 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 mag- net at the back of the 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 magnet, use
the crosshatch pattern. Make sure there is no blur or bend lines occur. If the blur or bend are serious, adjust the location of compensation magnet to make it better.

gle 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 1. Fix the wedges in a position so that the deflection
york neck is at the center of top bottom and left right. (Straight line and without any blur horizon- tal / 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 york. (Refer to Fig.6-1 and 6-2.)
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 york. (Refer to Fig.6-3.)
4. After confirm that there is no problems on the
entirescreen,bondeach wedge on CRTand glass tape on it. Fastening the screws of DY and mag- net 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 on the top and bottom of the screen, adjust DY by swing rightward and leftward. (Refer to Fig.6-4.)
