IMPORTANT SERVICE NOTES
Maintenance and re air of this receiver should be done by qualified service personnel onry. SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE
When servicing the high voltage system, remove static charge from it by connecting a 10 kohm 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. 2. 3. 4. Picture tube in this receiver employs integral implosion protection. Replace with tube of the same type number for continued safety. Do not lift picture tube by the neck. Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely.
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 hazardous radiation with prolonged exposure at close range, the following precautions should be observed:
1. 2. When repairing the circuit, be sure not to increase the high voltage to more than 27.3kV, (at cut-off) for the set. To keep the set in a normal operation, be sure to make it function on 25.3kV + 15kV (at beam 1 .I mA) in the case of the set. The set has been factory -Adjusted to the above-mentioned high voltage. If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work, DO not substitute a picture tube with unauthorized types and/or brands which may cause excess X-ray radiation. .I
3.
BEFORE RETURNING THE RECEIVER
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 lodged between the chassis and other metal parts in the receiver. 2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechanical insulators etc.

Convergence in Fig. d: Insert wedge "b" deeply between the deflection yoke and CRT, and tilt the d e f l e c t i o n y o k e t o l e f t u n t i l t h e misconvergence shown in Fig. d is corrected. 6. Stick the three wedges onto the CRT, and apply glass tapes thereon. 7. Apply lacquer to the deflection yoke screw, magnet unit (made of purity, 4-pole and 6pole magnets) and magnet unit screw. After the adjustment, receive either the Red or the Blue signal and check that there is no mixture with the other colour signal.

DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTE:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACEINC PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
NOTE:
1. The unit of resistance "ohm x is omitted (K = 1000 ohms, M = Meg ohm). 2. All resistors are l/8 watt, unless otherwise noted. 3. A/I capacitors are pF., unless otherwise noted P =L# 4. The diodes, whose parts code is not described, are the lSSll9. 5. All resistors are 118 W, unless otherwise noted.
VOLTAGE MEASUREMENT CONDITIONS:
SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR 1. Voltages without parenthesis measured with 3000 @I B & W or Color Signal. 2. The voltage in parenthesis represents the value measured with no signal. 3. All the voltages were measured by using a high impedance voltmeter.
SERVICE PRECAUTION:
The area enclosed by this line (- I - ) is direct/y 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.
WAVEFORM MEASUREMENT CONDITIONS:
1. The co/our bar signal applied to the TP40 1 is 1 .BVp-p. 2. The tuner AGC voltage is approximately 4V.
