Give complete “SERVICE REF. NO.” for partsorder or servicing. It is shown on the rating plateat the cabinet back of the unit.
This T.V. receiver will not work properly inforeign countries where the televisiontransmission system and power source dif-fer from the design specifications. Refer tothe specification table.
1: An isolation transformer should be connected in thepower line between the receiver and the AC linewhen a service is performed on the primary of theconverter transformer of the set.
2: Comply with all caution and safety-related notes pro-vided on the cabinet back, inside the cabinet, on thechassis or the picture tube.
3: When replacing a chassis in the cabinet, always becertain that all the protective devices are installedproperly, such as, control knobs, adjustment coversor shields, barriers, isolation resistor-capacitor net-works etc.. Before returning any television to thecustomer, the service technician must be sure thatit is completely safe to operate without danger ofelectrical shock.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially con-structed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must bethe 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 thisservice 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 highvoltage check to maintain the high voltage within the specified limits.
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 whichsafety can be of special significance. It is particularly recommended that only parts designated on the parts listin this manual be used for component replacement designated by mark . No deviations from resistancewattage or voltage ratings may be made for replacement items designated by mark .

When an abnormality occurs during TV reception, it causes pin 23 of the Processor to go continually Low (lessthan 2.0V) for about 2 second. The CPU detects that this has occurred and outputs the signal from pin 36 to switchoff the power supply lines.
Releasing the protective circuit and restoring power supply
To release the protective circuit and restore power supply, turn the power to the TV set OFF and then ON again viaeither the main power switch or the ON-OFF button on the remote control. This will work only if the power supplytrouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be restored and thecircuit will have to be repaired.
This TV set has a built-in power supply protection circuit.It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality occursduring TV reception, the TV set goes to the stand-by mode.

CAUTION: The Convergence and Purity adjustments have been made at the factory. Readjustmentshould be made only after picture tube or deflection yoke replacement, following the steps below:
PURITY ADJUSTMENT1. Demagnetize the picture tube and receiver using an external
degaussing coil. When replacing picture tube or deflectionyoke, mount deflection yoke and purity-convergence magnetsassembly properly, see figures 1 and 4.
2. Turn Red and Blue guns off and provide only Green raster.Rotate Screen control to fully counterclockwise. Rotate Redand Blue Bias controls fully counterclockwise. Slowly rotateGreen Bias control clockwise to produce Green raster.
3. Loosen the screw holding the Deflection Yoke and remove the3 Rubber Wedges, and slide the Deflection Yoke fully forward.
4. Rotate and spread the Tabs of the two Purity Magnets to cen-tre the vertical green belt in the picture screen. The PurityMagnets are also adjusted to obtain vertical centring of theraster.
5. Slowly slide the Deflection Yoke backward until a uniformgreen screen is obtained.
6. Check the purity of the red and blue screens for uniformity,turn off other colours to check this (use bias controls).Readjust the yoke position if necessary until all screens arepure.
7. Adjust each Bias control and screen control to obtain whiteraster. Refer to Gray Scale Adjustment. If part of the picturescreen is coloured, adjust the Deflection Yoke position forwardor backward slightly.
8. Tighten the mounting screw of the Deflection Yoke. AdjustConvergence next.
CENTRE CONVERGENCE ADJUSTMENT1. Use a dot crosshatch pattern signal.2. Turn Red and Blue guns on and turn off Green gun. Adjust the
angle between the Tabs of the Four Pole Magnet 1 and 2, andsuperimpose the Red and Blue vertical lines in the centre areaof the picture screen. Refer to figure 2.
3. Keeping the mutual angle of the Tabs of the Four Pole Magnetturn them together to superimpose the Blue and Red horizon-tal lines in the centre area of the picture screen. Refer to fig-ure 2.
4. Turn Green gun on and adjust Six Pole Magnet 3 and 4 thatthe Green line superimposed on the Red/Blue lines.This is the same procedure used in steps 2 and 3.Refer to figure 3.
OUTER AREA CONVERGENCE ADJUSTMENTSlightly loosen the screw holding the Deflection Yoke. Adjust theDeflection Yoke to converge the detail in the outer area (left sideand right side) of the picture screen by orbital movement of thefront of the Yoke, then secure the Deflection Yoke in appropriateposition by putting the wedges as illustrated. Tighten screw hold-ing the Deflection Yoke.

Product safety should be considered when acomponent replacement is made in any areaof a receiver.
Components indicated by a mark in thiscircuit diagram show components whose values have special significance to productsafety. It is particularly recommended that onlyparts specified on the part service manual beused for components replacement pointed outby the mark.
CIRCUIT DIAGRAM NOTICE:1. All resistance value are in ohms, K=1,000, M=1,000,000.2. All resistance rated wattages are 1/6W unless otherwise noted.3. Excepting electrolytic capacitors, all capacitance values of less than 1
are expressed in µ F and more than 1 are pF.4. All capacitance rated voltages are 50V unless otherwise noted.5. All inductance values are in µ H.6. Voltage readings take with a "VTVM" are from point indicated chassis
ground. Voltage readings taken by using PAL colour bar signal are with all controls at normal position. Some voltage may vary with signalstrength.
7. Waveform were taken with PAL colour bar and controls adjusted for normal picture. Waveforms were taken by using a wide band oscillo-scope and a low capacity probe.
8. This circuit diagram covers a basic or representative chassis only.There
may be some components or partial circuit differences between theactual chassis and the circuit diagram.
9. Parts specified with "X" are not installed in this model.10. Parts specified with "J" are just jumper wires.
THE SERVICE PRECAUTION:The area enclosed by this line( ) is directly connected with AC mains voltage.When servicing the area, connect an isolating transformer between TV receiver and ACline to eliminate hazard of electric shock.
