[Convergence Adjustment]
. Preparation
1. Input the MODE9 480/60p (525p) cross-hatch signal
to the BKM-68X (analog component input adaptor).
2. Press the 16 : 9 button to set 4 : 3 mode.
. Convergence adjustment
1. Minimize the vertical mis-convergence in the center at
the left-most end and at the right-most end of screen
using the DY correction reactors XBV and XCV.
* Because TLV is used for horizontal trapezoidal
distortion adjustment, adjust the convergence while
maintaining the correct adjustment of the horizontal
trapezoidal distortion correction only when MSV is
extremely poor.
2. Adjust the following data so that the mis-convergence
becomes minimum at the top and bottom parts of the
screen. (Keep the H STAT data to be 128, and do not
change it to any data other than 128.)

These adjustment menus are located in the SYSTEM
CONFIGURATION menu → MAINTENANCE →
DEFLECTION (4/5).
3. Copy the respective adjustment data into all modes.
Then confirm the vertical and horizontal convergence
again. If any mis-convergence is noticed, adjust the
convergence again.
