IMPORTANT SERVICE NO TES
Maintenance and repair of this receiver should be done by
qualified service personnel only .
SERVICING OF HIGH VOLTAGE SYSTEM AND
PICTURE 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 f ollowing
precautions should be observed:
1. 14BM2 : When repairing the circuit, be sure not to increase the high volt-
age to more than 25.5 kV (at beam 0.1 µA) for the set.
20BM2 : When repairing the circuit, be sure not to increase the high volt-
age to more than 28.0 kV (at beam 0.1 µA) for the set.
21BM2 : When repairing the circuit, be sure not to increase the high volt-
age to more than 28.0 kV (at beam 0.1 µA) for the set.
2. 14BM2 : To keep the set in a normal operation, be sure to make it function on
22.8 kV
± 1.5 kV (at beam 800 µA) in the case of the set. The set has
been factory - Adjusted to the above-mentioned high voltage.
20BM2 : To keep the set in a normal operation, be sure to make it function on
24.5 kV
± 1.5 kV (at beam 1,100 µA) in the case of the set. The set has
been factory - Adjusted to the above-mentioned high voltage.
21BM2 : To keep the set in a normal operation, be sure to make it function on
24.8 kV
± 1.5 kV (at beam 1,100 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 for get 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 follo wing 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-capacity networks, mechanical insulators etc.

ADJUSTMENT PRECAUTIONS
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 Short JA122 & JA124 for 1 second and release to switch to the service mode position,
and the microprocessor is in input 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 Short JA122 & JA124 for 1 second and release to switch to the normal mode (OFF)
position, and the microprocessor is in out of the service mode.
2. Factory Presetting.
1 Short JA122 & JA124 for 1 second and release to switch to the service mode position
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 pages 4, 5 & 6.
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 short JA122 & JA124 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 ma y possibly generate e xcessive Beam
current.
3. For reference please check with memory map

1. Receive "PAL COLOUR BAR" signal.
» Signal Strength: 57 ±1 dBµV (75 ohm open)
2. Connect the oscilloscope to TP201 (Tuner’s
AGC Terminal) as shown in Fig. 3.
3. Call "AGC" mode in service mode. Adjust the
"AGC" bus data to obtain the Tuner output pin
drop 0.1 V below maximum voltage.
4. Change the antenna input signal to
63~67dBµV , and mak e 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 ohm signal strength
gauge, when not using 50/75
impedance adapter, signal
strength is 52

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.

(14").
2. Degauss the CRT enough with the degausing
coil.
Note: Follow the Job Instruction Sheet to ad-
just the magnetic field.
Vertical Bv : +0.030 mT
(0.30 gauss)
Horizontal Bh : +0.020 mT
(0.20 gauss)
(Reference: page 8/21)
3. Maintain the purity magnet at the zero magnetic field and keep the static convergence
roughly adjusted.
4. Observe the points a, b as shown in Fig. 4-1
through the microscope. Adjust the landings
to the rank A requirements.
5. Orient the raster rotation to 0 eastward.
6. Tighten up the deflection coil screws.
» Tightening torque: 108 ± 20 N (11 ±2 kgf)
7. Make sure the CRT corners landing meet the
A rank requirements. If not, stick the magnet
sheet to correct it.
Note: This adjustment must be done after
warming up the unit for 30 minutes
or longer with a beam current over
700
µA. (21" & 20")
(For 14", the beam current should be
over 500

Static convergence
1. Turn the 4-pole magnet to a proper opening
angle in order to superpose the blue and red
colours.
2. Turn the 6-pole magnet to a proper opening
angle in order to superpose the green colour
over the blue and red colours.
Dynamic convergence
1. Adjust the convergence on the fringes of the
screen in the following steps.
a) Fig. 5-1: Drive the wedge at point “a” and
swing the deflection coil upward.
b) Fig. 5-2: Drive the wedge at points “b” and
“c” and swing the deflection coil
downward.
c) Fig. 5-3: Drive the “c” wedge deeper and
swing the deflection coil rightward.
d) Fig. 5-4: Drive the “b” wedge deeper and
swing the deflection coil leftward.
2. Fix all the wedges on the CRT and apply glass
tape over them.
3. Apply lacquer to the deflection yoke lock screw ,
