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.

Model No: 21WHP3-Bn
Version 1.0

5

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.

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.

GENERAL DESCRIPTION

AKPH02 chassis series are applied in A14P01/A21P01 respectively which uses
mainly Philips’ advanced UOC-ultimate chip TDA935X/6X/8X and I2C-bus
controlled IC. With combination of microcontroller and small signal processor, the
TDA935X/6X/8X series feature high-integration, high-performance-to-price ratio and
high-reliability and advanced functions with fewer external components, which
provide much convenience for manufacturing and technical service.

Table 1 provides A14P01/A21P01 mainly ICs and functions.

SIGNAL PROCESS

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.

SAFETY CAUTIONS FOR PRODUCTS

Many electric and mechanical components in AKPH01 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.

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

Check L452, VD436, C467,C455,especial in inductive components and connector

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 program protected.

The detail checking and repairing steps are as follow:

This failure is usually cause by the circuit of character generated and located. Most of reasons are that the horizontal and vertical flyback pulse signals do not come to UOC.
We can judge this failure by measuring the wave of the character in an oscilloscope.
