WARNING
The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power
receptacle, when servicing this chassis. To prevent electric shock, do not remove cover. No user – serviceable
parts inside. Refer servicing to qualified service personnel.
SERVICE MANUAL
In the interests of user-safety (Required by safety regulations in some countries) the set should be re-
stored to its original condition and only parts identical to those specified should be used.

IMPORTANT SERVICE NOTES
Maintenance and repairing of this receiver should be done by quali- fied service personnel only. SERVICE OF HIGH VOLTAGE SYSTEM AND PIC- TURETUBE
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 following precautions should be observed:
1.
*If there is a possibility that the high voltage fluctuates as a result of the repairing,
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 RETURNINGTHE 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.
2.
When repairing the circuit, be sure not to increase the high voltage to more than 28.0kV(at beam 0
µ
A) for the set.
To keep the set in a normal operation , be sure to make it function on 24.8kV
±
1.5kV(at
beam 1100
µ
A) in the case of the set.
The set has been factory - Adjusted to the above mentioned high voltage.

ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I
2
C bus control and in the conventional
analog manner. The adjustments via the I
2
C bus control include preset-only items and variable data.
1. Setting the service mode by the microprocessor.
1. Short JA 137 & JA 138 for 1 second and release to switch to the service mode position, and the
microprocessor is in input mode. (Adjustment through the 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 JA 137 & JA 138 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 JA 137 & JA 138, then turn on the main power and release to switch to the Service Mode position.
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 5 & 6. 3. Make sure the data need modification not (Initial data).
Note: Once the chassis has been assembly together and ready to be POWER ON for the FIRSTTIME,
make sure to short JA137 & JA138 to switch to the service mode position first and then turn on the main power switch (See 2-1above).
Precaution: If haven't done this initialization, it may possibly generate excessive Beam current.
3. For reference please check with memory map
(GA-1 Series type RH-iX3368CEN6)
 
CAUTION: Make sure TV set is in "Normal condition" before switch to Service Mode for adjustment.

PIF ADJUSTMENT
No. Adjustment point Adjusment conditions / procedre Waveform or others
Tuner IFT ( PRESET )
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 80dBuV. 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 sureto keep the tunercoverin position
duringthisadjustment.
RF-AGC TAKE OVER POINT AD- JUSTMENT (I2C BUS
CONTROL)
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 0.1V 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 ohm signal
strength gauge, when not using 50/75 impedance adapter, signal strength is 52±1dBµV(75 ohm open), in-
stead of 57±1dBµV (75 ohm
open).

PURITY ADJ. 1. Receive the GREEN-ONLY signal. Adjust the
beam current to ~700µA.
2. Degauss the CRTenough with the degausing coil.
Note: Follow the Job Instruction Sheet to ad-
just the magnetic field. Vertical Bv: +0.030mT (0.30 gauss) Horizontal Bh: +0.020mT (0.20 gauss) (Reference: page 6)
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 landing 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.
Note: Set the service mode by JA137&138
(short) then press factory process R/C RGB key to change to RGB mono colour mode.
* For the following colours press R/C RGB key to
change.

(To be done after the purity adjustment.
1. Receive the "Crosshatch Pattern" signal. 2. Using the remote controller, call NORMAL mode. STATIC CONVERGENCE 1. Turn the 4-pole magnet to a proper opening an-
gle in order to superpose the blue and red col- ours.
2. Turn the 6-pole magnet to a proper opening an-
gle 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,
magnet unit (purity, 4-pole, 6-pole magnets) and magnet unit lock screw. Finally received the Red-only and Blue-only sig- nals to make sure there is no other colours on the screen.

Remark 1. Before CRT cutoff adjustment, SUB-BRIGHT,
DRI-RS/RW/RC, DRI-GS/GW/GC, DRI-BS/BW/ BC, CUT-R and CUT-G must be INITIAL DATA.
2. CRT Cutoff adjustment must be done inside a
dark room.
1. SwitchTV to VIDEO mode,BLUE BACK OFF, with
NO VIDEO signal.
2. Press R/C to set Picture Normal condition. 3. First, off the screen by adjust screen variable re-
sistor.
*4.Next, checking AKB circuit function by slowly in-
crease screen variable resistor until colour raster suddenly on and off (AKB start function).
5.Then continue adjust until retrace line appear. 6. Finally, slowly decrease the screen variable re-
