Auto diagnosis feature
This receiver incorporates a new auto-diagnosis
feature. With this new feature will be easier for the
technicial to detect the failures. There is a LED located
by the keyboard on the front panel, this LED will start
flashing when a failure is detected by the circuits
located in specific areas, depending on how many
times the LED is flashing, this will tell you what circuit
should be checked.
Make a count of flashing and see Table 3.
Please use this feature effectively especially for
intermittent problems.
Table 3: SOS of front LED
After the count:
Proceed to check that area, verify what board is the
problem located, this way the area to check will be
reduced until the failure is found.

H-PAR DAC to set to specification level.
6. Confirm that level of B is 280_V ± 50_V, adjust
V-PAR DAC to set to specification level.
7. Confirm that level of C is more tha 20 V, adjust
H-PAR DAC to set to specification level.

Convergence alignment template
The convergence alignment template is a grid
approximatelythesizeoftheviewingscreenusedto
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 59, 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:
47” Models: 1036mm horizontal X 584mm vertical.
