A signal must be applied to the set, for the Mode being adjusted,
while performing Convergence or Geometry alignments. This is
necessary to provide the correct Line and Frame sync to the
Convergence panel. Failure to do so will result in an out of
convergence picture when signal is applied to the set. The set must
be convergenced twice, once for PAL or SECAM and once for NTSC.
Since the Line and Frame rate is the same for PAL and SECAM, it is
not necessary to adjust for both.
The Serviced Technician should sit at least 5 to 10 feet from the front
of the screen while doing Convergence. Ensure that you are eye level
with the area of the screen you are adjusting.
When performing Digital Convergence, the adjustments are
interactive. A change in one quadrant will affect adjacent areas of the
screen. Several passes through the Convergence sequence may be
