CHAPTER 2. IMPORTANT SERVICE NOTES
[1] IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only.
1. SERVICE 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 the same type number of picture tube 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.
2. 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, please make sure do not increase the high voltage of the set to more than 30.0kV (at beam 0µA).
2) To keep the set in a normal operation, please make sure it’s function at 26.5kV ±0.5kV (at beam 1000µA). 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 unauthorizerd types and/or brands which may cause excessive X-ray radiation.
3. 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-metal control knobs, insulating materials, cabinet backs, adjustment and compartment covers or
shields, isolation resistor-capacity networks, mechanical insulators etc.

CHAPTER 3. ADJUSTMENT PRECAUTIONS
[1] 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.
CAUTION: Make sure TV set in "Normal condition" before switch to Service Mode for adjustment.
1. Setting the service mode by the microprocessor.
i) Press SERVICE key on the remote controller to set the TV set to SERVICE mode position, and the microprocessor is in input
mode. (Adjustment through the I2C bus control).
ii) Press the MENU key on the remote controller to get ready to select the mode (Adjustment mode, Setting mode, Check mode and Option
mode) one by one.
iii) Press the CH DOWN / UP key on the remote controller to select the item in Adjustment mode, Setting mode or Option mode.
iv) Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified. Please wait approximately 200 msec for data storage
in EEPROM before select to another mode.
v) In Check mode the data cannot be changed.
vi) Press the SERVICE key again, it will switch to the NORMAL mode position, and the microprocessor is out of the SERVICE mode.
2. Factory Presetting.
i) Power ON the TV set, press the SERVICE key on the remote controller, then press both the CH UP and VOL UP button on the set
simultaniously for 5secs. Initial values are automatically preset, only when a new EEPROM is used.
ii) The initial data are preset as listed in page 3-7 to 3-13.
iii) Make sure the data need modification or not (Initial data).
Precaution: If haven't done this initialization, it may possibly generate excessive Beam current.
3. For reference please check with memory map RH-IXB226WJZZ. (See Page 4-1 ~ 4-16)

WHEN HOTEL MODE IS ON,
1. Max volume data is determined by option setting HTL-VOL (O03)
2. Channel position after POWER ON is determined by option setting HOTEL-POS (O02) (if option setting HOTEL-POS
is not set, processing is according to last position data).
3. User data updates of EEPROM regarding the video and audio control is not allowed.
4. Preset mode is disable.
5. CH SETTING menu is not available.

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
showninFig.2.
Note: Be sure to keep the tuner cover in posi-
tion during this adjustment.

2. Connect the oscilloscope to TP201 (Tuner’s AGC
Terminal) as shown in Fig. 3-1.
3. Call "V01" mode in service mode. Adjust the "V01"
bus data to obtain the Tuner output pin drop
0.1~1.0V 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 dBµVtobesure
that there is no cross modulation beat.

2. PURITY ADJUSTMENT
No. Adjustment point Adjustment procedure/conditions Waveform and others
1. Receive the GREEN-ONLY signal. Adjust the
beam current to ~700 µA.
2. Degauss the CRT enough with the degausing coil.
Note: Follow the Job Instruction Sheet to adjust
the magnetic field.
(Reference: page 3-6)
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. 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: 108 ±20N(11±2kgf)
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
µ A.

1. Turn the 4-pole magnet to a proper opening an-
gle in order to superpose the blue and red col-

2. Turn the 6-pole magnet to a proper opening an-
gle in order to superpose the green colour over

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
