 Note: This service manual is only for professional service personnel’s reference. Before
servicing the unit, please read the following items carefully.

1. Safety instruction

Before servicing and aligning this equipment, please read the following “X-RAY RADIATION
PRECAUTION”, “SAFETY PRECAUTION” and “PRODUCT SAFETY NOTICE”.

1.1 X-ray radiation protection

1.1.1 Too high voltage will produce radiation harmful to human health. To avoid such risk, the high
voltage should be regulated within the limited value. The normal value of the high voltage of this
receiver is 26.5kV at 0.9mA.
Under any circumstances, the high voltage should not exceed 30kV. When the TV set needs to be
fixed, please follow the inspection procedures of high voltage in item 4.6.1 under this
instruction ”Inspection of high voltage”. It is suggested that the value of high voltage be recorded
as part of maintenance work. It is most essential at the same time to use precise and dependable
high voltage meter.
1.1.2 This set is equipped with X-ray over radiation (FS) protection circuit to prevent over radiation of
X-ray in the case of abnormal increase of B+ voltage in the set or the reverse capacitor is open
circuit. Whenever fixing the set, FS circuit must be checked according to the inspection
procedures as in item 4.6.2 of this instruction, ”X-ray radiation protection test” to make sure the
circuit functions well.
1.1.3 The only source of TV set producing X-ray is CRT. To avoid X-ray radiation during the whole
process, the exact same type of CRT designated in the detail list must be replaced, when there is
a need to change CRT.
1.1.4 Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION
protection. Please read the “Points of attention for products safety” before changing the
components, for the sake of safety.

1.2 Safety measures

1.2.1 When the TV set is working, the high voltage will be as high as approximately 30kV. When
adjusting the set after removing the cover or opening the back cabinet there will be risk of electric
shock, so
a) Before detaching the anode cap, please discharge it several times by grounding the anode of
CRT to earth many times to avoid electric shock.
b) Before moving the CRT, its anode must be thoroughly discharged. The CRT is a high vacuum
part. Once broken, its fragments will fly out violently. Therefore it must be very careful in
dismantling and loading it.
1.2.2 There are a lot of electronic and mechanical components in PCB that have safety related

1
 features. They are indicated with shadow in the circuit diagram. Please carefully read the detail
list before changing these components.
1.2.3 If the fuse is blown, please change it for the one designated in the list of components.
1.2.4 When changing resistors of 1w or bigger than 1w in PCB, make sure to separate them from the
PCB by10 mm.
1.2.5 Make sure that the wire stays far away from the high voltage or high temperature components.
1.2.6 Check for the AC leakage current of the metal components exposed out of the cover such as
antenna terminal, screw, metal surface and control axis. Make sure that the cabinet of TV set is
absolutely safe in operation, free from any risk in electric shock. Insert the power supply plug
directly into the 110V (or 220V) AC socket (No isolate transformer will be applied during the test).
Use an AC voltage meter with sensitivity of 5 kΩ or higher per volt to measure the leakage
current according to the following steps:
First, connect in parallel a resistor of 1.5 kΩ,10 W and a 0.15 μF capacitor (AC type) between
the known good earthing connector (such as underground metal tube) and the exposed metal
parts out of the cabinet. Measure AC voltage across both terminals. Then exchange the two pins
of AC before re-measuring every exposed metal parts. The measured value of voltage should
not exceed 0.3V effective value, which corresponds to current.0.2mA. If the value exceeds this
specified value, aligning must be made at once.

respectively at every
exposed metal parts.

1.2. 7 DC voltage breakdown test

The following touchable parts must be subject to 1s anti voltage test before packing. The
voltage is applied between the plug pin of the power supply and the exposed metal parts for the
test and the volt value should be AC 3000V.

1.3 Points of attention for product safety
There are many electric and mechanical parts in this PCB that are related to safety. However, they
are often neglected from visual look. For changing the high voltage and high power parts, very
often it’s impossible to provide them with effective “X-ray radiation” protection. All these exchange
parts with safety characteristic are designated in the detail list. All the electronic parts with such
characteristics are indicated with shadow in the circuit diagram.
When changing these parts, please carefully check the detail list.

4.1 Enter into the factory debugging menu
Press the following buttons to enter by using the remote control (RC-A23):
DISPLAY → MUTE → MUTE → MUTE → enter into the factory
Press “sleep” button for pages upward, press “ ” button for pages downward, press “CH+/-” to
select alignment items and “VOL+/-” to adjust volume, press “MENU” to exit.
4.2 B+ voltage adjustment
Adjust RP501 and check B+ voltage (negative pole of VD509) by using DC voltmeter DC 200V, the
value of B+ voltage should be 111.0V±0.5V.
4.3 AGC adjustment

The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal
external components. The Fairchild Power Switch(FPS) consist of high voltage power Sense FET and
current mode PWM controller IC.
PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking,
optimized gate turn-on/ turn-off driver, thermal shut down protection, over voltage protection,
temperature compensated precision current sources for loop compensation and fault protection circuit.
Compared to discrete MOSFET and controller or RCC switching converter solution, a Fairchild Power
Switch(FPS) can reduce total component count, design size, and weight and at the same time increase

14
& efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective
design in quasi resonant converter as C-TV power supply.
