SAFETY PRECAUTIONSGENERAL GUIDE LINES

1. It is advisable to insert an isolation transformer in thea.c. supply before servicing a hot chassis.

2. When servicing, observe the original lead dress in thehigh voltage circuits. If a short circuit is found, replaceall parts that have been overheated or damaged bythe short circuit.

3. After servicing, see that all the protective devicessuch as insulation barriers, insulation papers, shieldsand isolation R-C combinations are correctlyinstalled.

4. When the receiver is not being used for a long periodof time, unplug the power cord from the a.c. outlet.

5. Potentials as high as 31,5kV are present when thisreceiver is in operation. Operation of the receiverwithout the rear cover involves the danger of a shockhazard from the receiver power supply. Servicingshould not be attempted by anyone who is notfamiliar with the precautions necessary when workingon high voltage equipment. Always discharge theanode of the tube.

6. After servicing make the following leakage currentchecks to prevent the customer from being exposedto shock hazard.

LEAKAGE CURRENT COLD CHECK1. Unplug the a.c. cord and connect a jumper between

the two prongs of the plug.2. Turn on the receiver’s power switch.3. Measure the resistance value with an ohmmeter,

between the jumpered a.c. plug and each exposedmetallic cabinet part on the receiver, such as screwheads, aerials, connectors, control shafts etc. Whenthe exposed metallic part has a return path to thechassis, the reading should be between 4M ohm and20M ohm. When the exposed metal does not have areturn path to the chassis, the reading must beinfinite.

LEAKAGE CURRENT HOT CHECK1. Plug the a.c. cord directly into the a.c. outlet. Do not

use an isolation transformer for this check.2. Connect a 2kΩ 10W resistor in series with an

exposed metallic part on the receiver and an earth,such as a water pipe.

3. Use an a.c. voltmeter with high impedance tomeasure the potential across the resistor.

4. Check each exposed metallic part and check thevoltage at each point.

5. Reverse the a.c. plug at the outlet and repeat each ofthe above measurements.

6. The potential at any point should not exceed1,4Vrms. In case a measurement is outside the limitsspecified, there is a possibility of a shock hazard, andthe receiver should be repaired and rechecked beforeit is returned to the customer.

X-RADIATION WARNING1. The potential sources of X-Radiation in TV sets are

the high voltage section and the picture tube.2. When using a picture tube test jig for service, ensure

that the jig is capable of handling 31,5kV withoutcausing X-Radiation.

NOTE: It is important to use an accurate periodicallycalibrated high voltage meter.1. Set the brightness to minimum.2. Measure the high voltage. The meter should indicate.

30,5kV ± 1kV.If the meter indication is out of tolerance, immediateservice and correction is required to prevent thepossibility of premature component failure.

3. To prevent any X-Radiation possibility, it is essentialto use the specified tube.

HOW TO MOVE THE CHASSIS INTO SERVICE POSITION

1. Remove 2 screws (A), as shown in Fig.4., and remove speaker assembly.2. Hold and lift the rear of the chassis and gently pull the chassis toward you, as shown in Fig.5.3. Release the respective wiring clips and move the EHT lead around to the left side of the CRT neck.4. Elevate the chassis as shown in Fig .6.5. Using a speaker screw, screw the chassis frame into the top speaker fixing rib (B), as shown in Fig.6.6. After servicing replace the speaker, and ensure all wiring is returned to its original position before returning the receiver

to the customer.

1. Set the +B voltage up as follows:-Adjust R811 so that B2 shows 148V±1V.

2. Confirm the following voltages.B9 5 ± 0,25V B10 5 ± 0,25VB5 12 ± 0,5V B11 33 ± 1,5VB4 15 ± 1V B7 8 ± 0,5VB12 26 ± 2V B8 6 ± 1VB3 36 ± 1,5V B13 13 ± 1VB1 205 ± 10V B14 14 ± 1V

CUT OFF / Ug2 Test1. Receive a Greyscale signal.2. Degauss the tube externally.3. Set the TV into Service Mode 1.4. Select Cut off mode.

To adjust Cutoff connect an oscilloscope to the Bluecathode. Press "STR" and adjust "cutoff" value using the"Yellow" and "Blue" buttons until the black level is 160V±5V,press "STR" to store the value. Remove the oscilloscope.Select Ug2 adjustment and adjust the screen VR until thedisplay shows "O.K."

FACTORY SETTINGSSelf-check is used to automatically check the bus lines and hexadecimal code of the TV set.To enter Self-Check mode. pressthe down (-/v) button on the customer controls at the front of the TV set, at the same time pressing the STATUS buttonon the remote control. To exit Self Check, switch off the TV set at the power button.

If the CCU ports have been checked and found to be incorrect or not located then " - - " will appear in place of "O.K.".

SCHEMATIC DIAGRAMS FOR MODELS

TX-25AS10D/MTX-25AS10F/M

(EURO-4H CHASSIS)

NOTE1. RESISTOR

All resistors are carbon ¼W resistor, unless marked otherwise.Unit of resistance is OHM (Ω) (k=1,000, M=1,000,000)

2. CAPACITORSAll capacitors are ceramic 50V unless marked otherwise.Unit of capacitance is µF unless otherwise stated.

3. COILUnit of inductance is µH, unless otherwise stated.

4. TEST POINTTest Point Position

5. EARTH SYMBOL

Chassis Earth (Cold)

Line Earth (Hot)

6. VOLTAGE MEASUREMENTVoltage is measured by a d.c. voltmeter.Measurement conditions are as follows:Power source a.c. 220V-240V, 50HzReceiving Signal Colour Bar signal (RF)All customer controls Maximum position

7.

Indicates the Video signal path

Indicates the Audio signal path

These schematic diagrams are the latest at time of printing and are subject to change without notice.

REMARKSa. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard.

b. Do not short circuit the hot and cold circuits as electrical components may be damaged.

c. Do not connect an instrument, such as an oscilloscope, to the hot and cold circuits simultaneously as this may causefuse failure. Connect the earth of the instruments to the earth connection of the circuit being measured.

d. Make sure to disconnect the power plug before removing the chassis.

NOTE1. The Power Supply Circuit contains a circuit area, which uses a separate power supply to isolate the earth connection.

The circuit is defined by HOT and COLD indications in the schematic diagram. All circuits, except the Power Circuit, areCOLD.

IMPORTANT SAFETY NOTICEComponents identified by mark have special characteristicsimportant for safety. When replacing any of these components, useonly manufacturers' specified parts.
