SERVICE MANUAL Colour Television
Product Code: 111376400
Original Version
Chassis Series: LA5-A
C7SA
Model No. 21TC663F
Service Ref. No. 21TC663F-00
(Argentina)
Give complete “SERVICE REF. NO.” for partsorder or servicing. It is shown on the ratingplate at the cabinet back of the unit.
This T.V. receiver will not work properly in foreign countries where the television trans-mission system and power source differ fromthe design specifications. Refer to the specifi-cation table.
Video input: Phono jack 2 (1Vp - p, 75Ω)Audio input: Phono jack (R/L) 2 (436mVrms, more than 40KΩ)Video monitor output: Phono jack 1(1Vp - p, 75Ω)Audio monitor output: Phono jack (L/R) 1(436mVrms, less than 600Ω)Headphone Jack: Mini stereo jack 1
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 Adjustment-11. Enter the Service Menu
While pressing the MENU button on the television, press the Number Key 2 on the remote control unit.The Service Menu now appear.
IC802 (EEPROM) ReplacementWhen IC802 (EEPROM) is replaced, IC801 (CPU) will automatically write the initial reference data into IC802 for basic TV operation.However, the bus data should be checked and some bus data should be set up before attempting the service adjustments. (Seepages 9 ~ 10 for detailed information.)
Initial Bus Data SetupNote: When IC802 (EEPROM) is replaced, following Service Menu should be set up for proper TV operation before attempting the
service adjustments.

Service Adjustment-4
Horizontal Width Adjustment1. Receive a monochrome circular pattern.2. Set the brightness and contrast to maximum.3. If the picture is too wide, or narrow, cut or short “JP436”
on the main unit. When JP436 is shorted, the horizontalwidth increase. When JP436 is cut, the horizontal widthdecrease.
Important note: When the JP436 is cut, it’s gap must be more than 5mm to prevent sparks.
HORIZ. WIDTH AND 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.

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, itcauses pin 27 of the CPU to go continually Low volt-age for about one second. The CPU detects that thishas occurred and outputs the signal from pin 31 toswitch off the power supply lines.
Releasing the protective circuit and restor-ing 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 theremote control. This will work only if the power supply trou-ble was temporary. If there is permanent trouble such as adamaged circuit, power cannot be restored and the circuitwill have to be repaired.
Protection Circuit
F.B.T.
1. Connect a DC voltmetre to TP-”+B +130V” and the ground. Set the +B adjustment control (VR651) to middle range.
2. Set the brightness to normal and contrast to maximum.3. Tune the receiver to an active channel and synchro-
nized picture.4. Adjust +B voltage to 130± 0.5 volt DC by using VR651.

High Voltage Check
Note: +B (+130V) Voltage Adj. and Grayscale Adjustmentmust be completed before attempting High Voltage Check.
4. Connect high voltage voltmeter negative lead to ground,and connect + lead to anode of picture tube.
5. Tune receiver to an active channel and confirm TV is operating properly.
6. The high voltage must be 25KV ± 1KV and less than 28KV at 0 beam current (Brightness and contrast minimum setting).
Note: If the picture tube is replaced, check the high voltage. The horiz. width adjustment affects the highvoltage. Therefore, re-check the high voltage.

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.
