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 this ser-vice manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specified limits, takenecessary corrective action. Carefully follow the instructions for + B1 volt power supply adjustment, and high volt-age 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 .

Service Information
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 abnormalityoccurs during TV reception, the TV set goes to the stand-by mode.
When an abnormality occurs during TV reception, it causes pin 27 of the CPU to go continually Low(less than0.75V) for about one second. The CPU detects that this has occurred and outputs the signal from pin 31 toswitch off 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 againvia either the main power switch or the ON-OFF button on the remote control. This will work only if the powersupply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot berestored and the circuit will have to be repaired.

Service Adjustments with Replacing Memory IC(IC802)
Note: The CPU (IC801) and memory IC (IC802) store the service adjustments data and controls data for each circuit.When the Memory IC(IC802) is replaced, some of the service adjustments should be readjusted to obtain the best performance. The necessary service adjustments are carried out by using the RC handset.Please set up the TV set with following steps [1] to [2].
[1] Initializing Procedure1. Put a new memory IC.2. Turn on the TV set.3. Press and hold the TV/AV Selector button on the TV set for more than 2 seconds. The following picture appears on
the screen.
4. Press the PROGRAMME UP on the TV set while the above On-Screen Display is still on the screen. The followingpicture appears on the screen.
This completes the initialization of memory IC.
Following shows the initialized contents of memory data by this procedure.- Plug & Play : No executed- Inhibit Data : Cancelled- Ch Skip Data : Cancelled- Sound Volume Data : 10/63 steps.- Volume Lock : OFF- Tuning Lock : OFF- Music Mode : OFF- AV Start : OFF- Colour System : AUTO

(2) Receive a monochrome circular pattern.(3) Set the brightness and contrast to maximum.
The high voltage must be 21KV ± 1KV.
(4) Set the brightness and contrast to minimum (0 beam current).The high voltage must be less than 23.5KV.
NOTE:If the picture tube is replaced, check the high voltage.
HIGH VOLTAGE CHECK
(1) Receive the monochrome circular pattern.(2) Set the brightness to normal and contrast to maximum.(3) Adjust the focus control on the F.B.T. for the best focus
on the screen centre.

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.
