When the Convergence error is small, a touch up
Convergence will be all that is necessary. Do not adjust
Green Geometry while in this mode. A compete in-depth
Convergence is required when the Small Signal Module
(SSM) or the Convergence Memory IC, has been replaced.
If the SSB (Small Signal Board) or the Large Signal Board
(LSB) has been replaced, a complete in-depth Geometry
should be completed before Convergence is adjusted. The
Geometry alignment should not be necessary if the SSB or
LSB have not been changed.

Touch-up Convergence Adjustments
Enter the Digital Convergence Mode (DCM) by entering 0-6-
2-5-9-7-(Status or Index) on the Remote control. The
following menu will appear:
Select an active channel or Aux Input. A signal must be
applied to the set when performing convergence. If any
Customer Adjustments need to be made, the Menu button
can be used to toggle between the Customer Menu and
DCM. The MPOSD ADJUST is used to center the Customer
Convergence grid. A highlighted cross will appear along with
the Convergence alignment grid. The highlighted cross
should be centered onto the center of the Convergence grid.
To perform a Touch Up Convergence, highlight SELECTION
and press the right cursor button on the remote. The
following menu will appear:
Selections STORE, RESTORE FACTORY, and RESTORE
DEFAULT are not shown after selecting SELECTION. Press
the cursor down button on the Remote for these selections to
appear. RESTORE FACTORY loads Convergence defaults
from the Factory Loaded section of the Convergence
Memory IC. RESTORE DEFAULT loads Convergence
defaults from the sets software.
