CABINET- REAR VIEW
HORIZONTAL SWEEP CIRCUIT ADJUSTMENTS
Turn the set on and tune in a TV station, preferably a test pattern.
Adjust the horizontal frequency slug (Bl) to the mid-position between the two points where the picture falls into synchronism,
not out of synchronism.
Turn the horizontal position control until the right side of the raster is visible.
Turn up the brightness, and reduce the contrast until the normally blanked edge of the raster is visable.
There should be a vertical gray strip about 1/4 inch wide at the right edge of the raster adjacent to the picture. Still further
to the right there may be a darker strip. If the darker strip is visable, and is over 3/16 inch wide, or if the lighter strip is not
present, the phasing control (B2) is not properly adjusted. B2 should be adjusted so the left edge of the darker strip Is at the
extreme right edge of the raster, (almost to the point of disappearing).
HORIZONTAL LINEARITY ADJUSTMENTS
The horizontal drive control has the effect of spreading or compressing the right side of the picture. This control is pre-set
at the factory and normally will not require adjustment in the field.
Adjust the horizontal size slug (B3) until the picture fills the mask horizontally.
Adjust the horizontal linearity slug (B4) until the picture is symmetrical from left to right.
