Color Display Module Adjustments - HP 16500A Service Manual

4-5. Color Display Module Adjustments

Description:
The Color Display Module is adjusted to compensate for external magnetic influences causing
misconvergence.
DO NOT continue with this procedure before first degaussing the CRT screen
using the rear panel degaussing switch. In extreme cases of magnetism, it may
be necessary to degauss the CRT using a conventional external television-type
degaussing coil. During any of the following adjustments, the CRT module must
face west.
Equipment Required:
Nonmetallic Adjustment Tool.......................................................................HP Part Number 8710-1355
Procedure:
The following adjustments are broken down into adjustment groups. The
sequence of the adjustment groups must be followed due to the interaction and
dependency of one adjustment to another. The adjustment group sequence is
shown in the adjustment flow diagram in figure 4-11. There will be cases where
not all the adjustment groups will be used. For example, if the Geometry
Adjustment Group corrects the problem, this will be the only group used.
