Convergence alignment template
The convergence alignment template is a grid
approximately the size of the viewing screen used to
ensure the proper size and shape of the alignment
rasters. It is 6 blocks across by 6 blocks high. The grid
dimensions vary with the mode of operation.
Apply a convergence alignment template to the
viewing screen of the PTV. Make sure the center lines
are properly aligned. If a template is not available, one
can be created by following the instructions below.
Create a
convergence alignment template by
drawing a pattern, as in figure 15, in the actual
dimensions on transparent film or tracing paper. Start
with the Horizontal and Vertical Center Axis and work
outwards until the pattern is complete. Pay attention to
the actual dimensions of the pattern.
Grid dimensions:
51” Models: 1039mm horizontal X 779mm vertical.
Note: A convergence alignment template, part
number TXFQD01ESER1 for 51”
( same as for 47” ), is available through
Matsushita/Panasonic Services.
