SAFETY INSTRUCTION
WARNING: BEFORE EXAMINING AND SERVICING THIS CHASSIS,
READ CAREFULLY THE FOLLOWING SAFETY INSTRUCTIONS.
X-RAY RADIATION PRECAUTION
1. 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.
2. 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.
3. 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.
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.
SAFETY CAUTIONS FOR PRODUCTS
Many electric and mechanical components in AKTP01 /02 chassis have special safety performances,
which are always neglected. Even if replacing them with some components with the same voltage and
power, you can not get effective protection to X-ray. In the circuit diagram, these special electric
components are indicated by the special mark and on the shadow. When replacing any of them,
use the one with the same specifications as the original’s. Otherwise, it may cause X-ray radiation and
damage to overall safety.

CIRCUIT ADJUSTMENTS
GENERAL INFORMATIONS
All adjustment are thoroughly checked and corrected when the receiver leaves the factory. Therefore
the receiver should operate normally and produce proper color and B/W pictures upon installation.
However, several minor adjustments may be required depending on the particular location in which the
receiver is operated.
This receiver is shipped completely in carton. Carefully draw out the receiver from the carton and
remove all packing materials. Power cord into a convenient 220 volts 50 Hz AC two pin power outlet.
Turn the receiver ON. Check and adjust all the customer controls such as BRIGHTNESS, CONTRAST
and COLOUR Controls to obtain natural color or B/W picture.
AUTOMATIC DEGAUSSING
A degaussing coil is mounted around the picture tube so that external degaussing after moving the
receiver is normally unnecessary, providing the receiver is properly degaussed upon installation. The
degaussing coil operates for about 1 second after the power to the receiver is switched ON. If the set is
moved or faced in a different direction, the power switch must be switched off at least 30 minutes in
order that the automatic degaussing circuit operates properly. Should the chassis or parts of the cabinet
become magnetized to cause poor color purity, use an external-degaussing coil. Slowly move the
degaussing coil around the faceplate of the picture tube, the side and front of the receiver and slowly
withdraw the coil to a distance of about 2m before disconnecting it from AC source. If color shading
still persists, perform the COLOUR PURITY ADJUSTMENT and CONVERGENCE
ADJUSTMENTS procedures.

2. 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 “Signalinput 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.

we only check the sound signal processing and sound amplification circuit. The
repairing method (B1) may be referred without picture. The detail checking and

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 XZ411, 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
2) The clock pulse: In TMPA88XX circuit, the clock pulse is generated by pin6 /
Television’ s remote-control system also needs reset circuit that can preset the values
in internal register. The circuit around pin6 of N204 is called auto-reset circuit. If
UOC detects errors in resetting, it will come to the state of programme protected.
The detail checking and repairing steps are as follow:
