In order to reduce the influence of geomagnetism on the set's picture tube, face it in an easterly or westerly direction. Switch on the TV set's power and degauss with the degausser. Fig. Input an all-white signal from the pattern generator. Set the Contrast and Brightness to normal. Set the pattern generator raster signal to all Red. Move the deflection yolk forward and adjust with the purity control so that the Red is at the centre and the Blue and Green take up equally sized areas on each side of the screen. Move the deflection yolk forward and adjust so that the entire screen becomes Red. Switch the raster signal to Blue, then to Green and verify the purity condition. When the position of the deflection yolk has been determined, fasten the deflection yolk with the screws. If the beam does not land correctly in all the corners, use magnets to correct it. Adjust the `G-cut-off', and the `B-cut-off' so that the White Balance becomes optimum. Press the button to return to TV operation. Fit the permalloy assembly to the rear of the CRT to correct the area at fault. a 6. 10. b PICTURE R - Drive G - Drive Permalloy c d Adj Adj Adj Adj Adj Adj 02 01 01 Adj Adj Adj B - Drive R - cut - off G - cut - off B - cut - off ID - start ID - stop ID - level Bellfo Sub Colour Sub Brightness 3-4. 3.
