Service Manual
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 6, 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 specifications 53” Models

Note: The convergence alignment templates, part
number
TXFQD01FSER for 53” and
TXFQD04ESER1 for 56”, are available through
