Horizontal and Vertical Size Check
1.
Apply monoscope pattern.

±
0.2 lines at “A”
and “B” and that vertical size is 3.5
±
0.1 lines at “C”
and “D” as indicated in Figure 52 with digital
convergence dissabled (MUTE to 1); If digital
convergence is enabled (MUTE to 0) vertical size
is 4.0
±
0.1 lines at “C”.
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 53, 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: 85.5mm Horizontal X 93mm Vertical.
56” Models: 1138mm Horizontal X 853mm Vertical.
61” Models: 1240mm Horizontal X 930mm Vertical.
Note: A convergence alignment template, part
number TXFQD01ESER for 51” and
TXFQD03ESER for 56” & 61”, is available
through Matsushita/Panasonic Services.
