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.

IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by
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 following
precautions should be observed:
1. When repairing the circuit, be sure not to increase the high voltage to more
than 23.7 kV
2. T o keep the set in a normal operation, be sure to make it function on 22.5 kV
kV (at beam 800 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.
qualified service personnel only .
± 1.5kV (at beam 0 µA) for the set.

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-capacity networks, mechanical insulators and etc.
ADJUSTMENT PRECAUTIONS
Ë
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.
Coution: Make sure TV Set is in "Normal condition" before switch to service mode for
adjustment
1. Setting the service mode by the microprocessor.
1 Make a short-circuit 137 and 138 for a 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 Make a short-circuit 137 and 138 for a second and release to switch to the normal mode
(OFF) position and the microprocessor is in out of the service mode.
2. Factory Presetting.
3
1 Make a short-circuit 137 and 138 for a 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 4-6.
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 make a short-circuit 137 and 138 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.
3. For reference please check with memory map
(GA-1AM Series type RH-iX3368CE Attachment)

1. Get the tuner ready to receive the E-9 CH
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 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 "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.

PURITY ADJ. 1. Receive the GREEN-ONLY signal. Adjust the
1
beam current to 500 µA.
2. Degauss the CRT enough with the degausing
coil.
Note :Follow the Job Instruction Sheet to adjust
the magnetic field.
Vertical Bv : - 0.050 mT
(- 0.50 gauss)
Horizontal Bh : + 0.020 mT
(0.20 gauss)
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. 1-1
through the microscope. Adjust the landings
to A rank requirement.
5. Orient the raster rotation to 0 eastward.
6. Tighten up the deflection coil screws.
» Tightening torque: 108N ± 20 N
(11kgf ± 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 500
µA.

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. a : Drive the wedge at point "a" and
swing the deflection coil upward.
b) Fig. b : Drive the wedge at point "b" and "c"
and swing the deflection coil downward.
c) Fig. c : Drive the "c" wedge deeper and
swing the deflection coil rightward.
d) Fig. d : 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

Remark
1. Before CRT cutoff adjustment, SUB-BRIGHT, DRIRS/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. Switch TV 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 resistor.
*4. Next, checking AKB circuit function by slowly increase
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 resistor
until screen retrace line cut off (Not Raster)
Note :
Must confirm the AKB function in set before continue
the next adjustment.
1. Call " SUB-BRI" in service mode. (Receive Crosshatch pattern with 5 black level windows)
*(2) Adjust the " SUB BRIGHT " bus data in order that
the line 1and 2 have the same darkness wherelse
line 3 is one step (data) brighter than line 2. Finally

1. Receive the "WHITE" pattern with BURST signal.
2. Press R/C to set Picture NORMAL condition.
3. Connect the DC miliammeter between TP602 (-)

4. Check Beam current should be around 800 µA.
5. Set it to service mode and adjust the DRI-GS, & DRIBS data to have a colour temperature of 12300°K (
white ). * Note .
6. Receive "WHITE" pattern, WITH BURST signal, and
set BRIGHTNESS Y by generator, to **10 cd/m2
(MINOLTA CA-100) by reducing LUMINATE Y signal.
7. Adjust "CUT-R" & "CUT-G" to get desired colour temperature #. Then go back NORMAL mode (HIGH
BRIGHT**) to check colour temperature.
If out of range, back to 1.
Note:This adjustment must be done after warm-
ing up the unit for 30 minutes or longer with
a beam current over 500
