Precautions in servicing
(1) If the convergence gets out of spec during servicing, call up the process mode and select the following sub-
jects.

Subject : R-CNV-H, R-CNV-V
G-CNV-H, G-CNV-V
B-CNV-H, B-CNV-V
(H: Horizontal adjustment, V: Vertical adjustment)
Adjust the above settings in the range of 0-4. When changing each setting from the initial setting of 2, however,
the 1280 x 1024 dot display area will have a fewer number of lines.
Example 1 : When the R-CNV-H setting is changed from 2 (initial) to 4, the number of lines will be from 1280 to
1278.
Example 2 : When the R-CNV-H, G-CNV-H and B-CNV-H settings are changed to 3, 3 and 4, respectively, the
display will be 1278 x 1024 lines. But when the above settings are switched to 2, 2 and 3, respec-
tively, the display will be 1279 x 1024 lines.
Preferably keep each setting as close to 2 as possible.
