SAFETY NOTICE
WARNING: BEFORE EXAMINING AND
SERVICING THIS CHASSIS, READ
CAREFULLY THE FOLLOWING
SAFETY INSTRUCTIONS.
X-RAY RADIATION PRECAUTION
1. The primary source of X-RADIATION in television receiver is the picture tube. The picture tube
is specially constructed to limit X-RADIATION emissions. For continued X-RADIATION
protection, the replacement tube must be the same type as the original including suffix letter.
Excessive high voltage may produce potentially hazardous X-RADIATION. To avoid such
hazards, the high voltage must be maintained within specified limit. Refer to this service manual,
high voltage adjustment for specific high voltage limit. If high voltage exceeds specified limits,
take necessary corrective action. Carefully follow the instructions for +B1 volt power supply
adjustment, and high voltage check to maintain the high voltage within the specified limits.
2. The EHT must be checked every time the receiver is serviced to ensure that the CRT does not emit
X-ray radiation as result of excessive EHT voltage. The nominal EHT for this receiver is 22KV at
zero beam current (minimum brightness) operating at AC 220V. The maximum EHT voltage
permissible in any operating circumstances must not exceed 25KV. When checking the EHT, use
the High Voltage Check procedure in this manual using an accurate EHT voltmeter.
3. The only source of X-RAY radiation in this receiver is the CRT. To prevent X-ray radiation, you
should use the same type of CRT when replacing it.
4. Some components used in this receiver have safety-related characteristics preventing the CRT
from emitting X-ray radiation. For continued safety, replacement component should only be made
after referring the Product Safety notice below.
SAFETY PRECAUTION
1. The high voltage in the TV reaches to 22KV when the TV is in operation. Be more careful during
opening the back cover.
a) The high voltage existing in the TV is very dangerous. Refer servicing to qualified personnel
only.
b) Before removing the high voltage cap. Discharge the anode of the CRT and the chassis in
case of electric shock.
c) Wear a pair of goggles when handling the CRT to avoid broken pieces damaging your eyes.
d) Do not hold the CRT neck in case of causing damage to the CRT.
2. When the power cord needs replacing, use the same one as that provided by AKIRA factory.
3. Voltage exists between the hot and cold ground when TV is in operation. Install a separation
transformer during repairing or connecting to any tester for the sake of safety. The power of the
separation transformer should be beyond rated overall power.
4. When replacing a burnout fuse, use the one with the same specifications as the original.
Model No: 14THS3/CE.doc
Version 1.0
Page 5

5. When replacing old wire, wind new one round the shaft to weld. When replacing components with
safety in performance, use the same type as that specified by AKIRA and install it in the former
way.
6. Never place wire near high-temperature or high-voltage components.
7. An isolation transformer should be connected in the power line between the receiver and the AC
line when a service is performed on the primary of the converter transformer of the set.
8. Comply with all caution and safety-related notes provided on the cabinet back, inside the cabinet,
on the chassis or the picture tube.
9. When replacing a chassis in the cabinet, always be certain that all the protective devices are
installed properly, such as, control knobs, adjustment covers or shields, barriers, isolation resistor-
capacitor networks etc.. Before returning any television to the customer, the service technician
must be sure that it is completely safe to operate without danger of electrical shock.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by mark in the parts list and the schematic diagram designate components in
which safety can be of special significance. It is particularly recommended that only parts designated
on the parts list in this manual be used for component replacement designated by mark. No deviations
from resistance wattage or voltage ratings may be made for replacement items designated by mark.

SIGNAL PROCESS
N801 (Video)
N161 (sound)
The TV signal enters into tuner (A201) from cable or antenna. Pin 10 and pin 11 of N301 are combined
to select the band. Pin 4 of N301 outputs PWM tuning signal. The 38.9MHz IF signal is coupled to
V308 (pre-amplify) and then to SAWF (Z301). After processed in the SAWF, the 38.9MHz signal gets
to pin 23 and pin 24 of OM8370. The IF circuit in OM8370 includes such unit as the AGC amplifying
circuit, 38.9MHz oscillator, PLL video demodulator, video amplifier, IF identify circuit and AFT
circuit. The demodulated signal (CVBS) comes from the pin 38 of OM8370, the sound signal comes
from the pin 44.
The internal CVBS signal needs norm identification then outputs from pin 38 of OM8370, via the trap
circuit (composed of the V351, Z351, Z354, V352 and so on) feeds back to the pin 40 of OM8370. The
RGB signal comes from pin51, Pin52, Pin53 of OM8370, and outputs to the CRT board. The internal
sound signal comes from pin 44 of OM8370 and then input to pin 1 and pin 12 of HEF4052BP. The
sound signals from RF and AV are selected in it. The selected signal is output from Pin 3 and pin13,
then input AN7522N (sound amplifier) or output from AV terminals.

HORIZONTAL AND VERTICAL CIRCUIT
Through Synchronous separating circuit, the video signal is divided into horizontal-Synchronizing
signal and Vertical-Synchronizing signal. The horizontal-Sync pulse coming from pin 33 is transferred
to the horizontal-drive transistor.
The cathode driving voltage 180V vertical drive voltage +15V and –15V are all generated from
FBT.
The vertical sawtooth waveform is generated on the pin 21 and 22, and then enters the vertical
amplifier STV9302A. STV9302A is a 7 pins vertical deflection circuit (2 Amperes) for DC-coupled
90° or 110° deflection systems with frame frequencies from 50 up to 120 Hz. one supply voltage for
the scanning and second voltage supply for the flyback are needed.
The vertical drive currents of OM8370 pins 21 and 22 are connected to input pins 1 and 7 of
STV9302A. The vertical scanning output is coming from pin 5 and feed back to pin 1 by R405. The
supply voltage is ±15V at pin 2 and pin 4. C406 is the pump capacitor.
POWER SUPPLY
The IC of KA5Q0765RT is adapted in this chassis; it is the product of Fairchild. It supplies four DC
voltages, one is the +B＝110V, another is Hcc＝26V, the third is 13V (the sound drive voltage), the
fourth is +16V. The +16V can generate the +8V, +5V and +3.3V by the special generators.

B Two-None (no picture, no sound)
The failure shows that the set does not display the picture but it has noise wave or blue background or OSD on the screen. This means that the circuits of power supply, horizontal scanning, vertical scanning
and video amplification are normal and they are not considered in the repairing. The failures are mainly in the small signal processing circuits.
Before checking these circuits, a kind of practical test method is introduced. It is called “Signal-input way ”. The detail is described as follow: We can use the resistance function of an analog multimeter,
connect the red pole (negative in ohm scope) on the circuit board ground, then touch softly the test point with another pole (black pole) in ohm scope meanwhile observe the reactivity on the output device.
Note : In the TV test, we mainly observe the noise wave on the CRT and listen to the noise voice liking as “Ka…..Ka” from the loudspeakers.

In this kind of failure, first of all we should observe if there is the picture on the CRT. It proves the small signal circuit to work correctly with the picture on the CRT and we only check the sound signal
processing and sound amplification circuit. The repairing method(B1) may be referred without picture. The detail checking and repairing steps are as follow.

If vertical deflection circuit does not work, this kind of failure will happen. In deflection yoke, there only has horizontal sweeping , the electron beam in the CRT only moves in the horizontal orientation , so
form this failure.
(While checking horizontal and vertical deflection circuit’ s failure , we have better to use an oscilloscope.)

This is a dangerous failure. It probable causes flashover and smoking inside the set. Don’ t let your TV work for a long time as this failure appears. Because the electron beam can not move in the horizontal
orientation, the failure should be in the horizontal deflection circuit. We mainly check the open-circuit fault in horizontal deflection circuit. The detail checking and repairing steps are as follow:
Check if there is bad solder between XS403, and the main board
E UOC does not work
In television, remote-control system is similar with the computer system. In theory , it can work if it holds two conditions as follow:
1) The power supply: In general, it is 5V, the error is not above 10% and the disturbance pulse is as small as possible.
2) The clock pulse: In TDA93XX circuit, the clock pulse is generated by pin58 / pin59 of N301 and 12M crystal oscillator.
Television’ s remote-control system also needs reset circuit that can preset the values in internal register. The circuit around pin57
of N204 is called auto-reset circuit. If UOC detects errors in resetting, it will come to the state of programme protected.
