the high voltage completely.

Maintenance and repair of this receiver should be done by qualified

service personnel only.

SERVICE OF HIGH VOLTAGE SYSTEM AND PIC-

TURE TUBE

When servicing the high voltage system, remove static charge from it by

Connecting a 10K ohm Resistor in series with an insulated wire(such as a

test probe) between picture tube dag and 2nd anode lead. (AC line cord

should be disconnected from AC outlet.)

1. Picture tube in this receiver employs integral implosion protection.

2. Replace with tube of the same type number for continued safety .

3. Do not lift picture tube by the neck.

4. Handle the picture tube only when wearing shatterproof goggles and after discharging

X-RAY

This receiver is designed so that any X-Ray radiation is kept to an absolute

Minimum. Since certain malfunctions or servicing may produce potentially

(at beam 0

hazardous radiation with prolonged exposure at close range, the following

precautions should be observed:

1. When repairing the circuit, be sure not to increase the high voltage to more than 26.0kV

\ If there is a possibility that the high voltage fluctuates as a result of the repairs,

Before returning the receiver to the user, perform the following safety Checks.

1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not

2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers,

DESCRIPTION OF SCHEMATIC DIAGRAM

SAFETY NOTES:

1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS.

2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.

IMPORTANT SAFETY NOTICE:

PARTS MARKED WITH " " ( ) ARE IMPORTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET.

SERVICE PRECAUTION:

THE AREA ENCLOSED BY THIS LINE ( CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK.

) IS DIRECTLY

NOTES:

1. The unit of resistance "ohm" is omitted. (K = 1000 ohms, M = Mega ohm).

2. All resistors are 1/16 watt, unless otherwise noted.

3. All capacitors are mF, unless otherwise noted. (P = mmF).

VOLTAGE MEASUREMENT CONDITIONS:

1. Voltages in parenthesis measured with no signal.

2. Voltages without parenthesis measured with 3mV B & W or Colour signal.

3. All the voltages in each point are measured with VTVM.

WAVEFORM MEASUREMENT CONDITIONS:

1. The colour bar generator signal of 1.0V peak applied at pin (24) of IC201.

2. Approximately 4V AGC bias .
