Static Convergence Adjustment - Sony TRINITRON BVM-14G1A Operation And Maintenance Manual

3-7-1. Static Convergence Adjustment

• Horizontal Static Convergence
1. Adjust RV501 (H STAT) of the C board so that the red
and green dots coincide in the horizontal direction at the
screen center.
2. If the blue dot is out of convergence from the red and
green dots:
• For the 14-inch model:
Perform HMC (horizontal misconvergence) correction
using the 6-pole magnet of the DY (See Fig. 1-2.).
(The 4-pole magnet of the DY is not used. Set to the
OFFSET state.)
• For the 20-inch model:
Perform HMC (horizontal misconvergence) correction
using the 6-pole magnet of the NTC (See Fig. 1-2.).
• Vertical Static Convergence
1. Adjust the V STATIC CONV data so that the red and
green dots coincide in the vertical direction at the screen
center.
Note: The V STATIC CONV adjustment menu is under
the E BOARD menu of the MAINTENANCE
menu.
2. If the blue dot is out of convergence from the red and
green dots:
• For the 14-inch model:
Perform VMC (vertical misconvergence) correction us-
ing the 6-pole magnet of the DY (See Fig. 1-2.).
(The 4-pole magnet of the DY is not used. Set to the
OFFSET state.)
• For the 20-inch model:
Perform VMC correction using the 6-pole magnet of the
NTC (See Fig. 1-2.).
