Refer to the specification table. An isolation transformer should be connected in the power dahasheet between the receiver and the AC line when a service is performed on the primary of the converter transformer of the set.

Comply with all caution and safety-related notes provided on the cabinet back, inside the cabinet, on the chassis or the picture tube. When replacing a chassis in the cabinet, always be certain that all the protective devices are installed properly, such as, control knobs, 2zd2634 covers or shields, barriers, isolation resistor-capacitor networks etc.

Before returning any television to the customer, the service technician must be sure that it is completely safe to operate without danger of electrical shock. To avoid such hazards, the high voltage must be maintained within specified limit.

Refer to this service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specified limits, take necessary corrective action. Components indicated by mark in the parts list and the schematic diagram designate components in which safety can be of special significance. It is particularly recommended that only parts designated on the parts list in this manual be used for component 2zd2634 designated by mark.

No deviations from resistance wattage or voltage ratings may be made for replacement items designated by mark. The option window will appear on the screen. To switch the option mode, use the Level up or down button. The data which is set in the option mode is stored into the memory IC automatically.

The following table shows the available option items and default setting mode. When the Memory IC IC 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]. Put a new memory IC. Turn on the TV set.

Enter to the Service Mode as explanation on next page. When initialised the memory IC are completed, TV set will in stand by mode, all of the setting data option data andservice adjustment data stored in the IC are reset to the default value. It is necessary to set the option settings and readjust the service adjustments listed on page and to re-tune all the channels. This completes the initialization of memory IC. Following shows the initialized contents of memory data by this procedure.

Press the Menu button on the TV set while the above On-Screen Display is still on the screen to reset all received channel. The display will changed in red colour. Wait for a view seconds until the TV is not receive the broadcasting signal. Then turn off the TV. When the dealer mode is executed, all received channels, picture settings and audio settings will be reset.

Do not attempt this adjustment with weak signal.

Set the brightness and contrast controls to maximum. Set the colour control to minimum. Turn back the screen VR to min.

Confirm high voltage does not exceed 32 KV at zero beam current. The Convergence and Purity adjustments have been made at the factory. Readjustment should be made only after picture tube datashdet deflection yoke replacement, following the steps below: Use a pattern generator which can output red, green, blue and white raster and crosshatch pattern signals.

Carry out 2sd634 adjustment first, and then carry out convergence adjustment. The deflection yoke may have several correction magnets attached to its outer edge. If replacing the picture tube, the positions of the magnets can be changed and they can be re-used, so remove these magnets and keep them safely so that they do not get lost. Place the picture so that its front faces west. Insert the power plug into a wall outlet, and then turn on the power for the TV and de-magnetize the TV using its own degaussing circuit.

Loosen the screw which is holding the deflection yoke with integrated purity magnetsand then move the deflection yoke forward as far as it will go. Remove the rubber wedge at this time. Turn off the red and blue raster so that only the green raster is on. Adjust the angle between the tabs wings on purity magnets to centre the vertical green belt in 2s2d634 picture tube screen.

See Figures 2 and 3. This adjustment can only be carried out by changing the angle, not by rotating the tabs up and down. Gently move the deflection yoke back to the position where the green band fills the whole of the picture tube screen, and then tighten the screw to secure the deflection yoke in place.

If there is any colour distortion around 2sd26634 edges, correct it by attaching magnets to the outer edge of the deflection yoke. The magnets should be attached so that the line running from the position of the distortion to the centre of the picture tube intersects the deflection yoke. The colours on the magnets indicate the north and south poles of the magnets. Attach the magnets in whichever direction causes the distortion to disappear.

See Figures 1 and 4. The south and north pole positions are shown as a guide. Switch the datasgeet to red and blue raster and check that there is no colour distortion.

If there is any distortion, adjust the angles of purity magnets tabs or the forwardback position of the deflection yoke, or change the attachment positions of the N correction magnets. Move the deflection yoke back and forth to adjust the purityFigure 2 Change the angle to adjust the green band so that it is centred in the screen.

After carrying out purity adjustment and before proceeding to convergence adjustment, provisionally insert the rubber wedge so that there is no vertical or sideways play in the deflection yoke. Display a crosshatch pattern. Vertical lines at screen centre Red and Blue Use the VR2 control 2se2634 Figure 8 at the top of the deflection yoke to correct the vertical line convergence at the centre of the screen.

Vertical lines at screen top and bottom Use the VR1 control see Figure 8 at the top of the deflection yoke to correct the vertical line convergence at the top and bottom of the screen. Horizontal lines at screen top and bottom Rotate the Deflection yoke to the left or right to correct the horizontal line convergence at the top and bottom of the screen. If vertical lines are intersecting at the top and bottom, use a screwdriver to adjust the Balance coil at the top of the deflection yoke.

Red BlueFigure 7 Adjust the angle and rotation of tabs 3 and 4 to align the vertical and horizontal lines. Refer to Figure 1, remove 14 screws. Pull off cabinet back and remove. It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality occurs during TV reception, the TV set goes to the stand-by mode. The CPU detects that this has occurred and outputs the signal from pin to switch off the power supply lines.

This will work only if the power supply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be restored and the circuit will have to be repaired.
