4.
If the V.STAT magnet is moved in the direction of the (a)
and (b) arrows, the Red, Green and Blue points move as
indicated below.
1.
[Moving horizontally], adjust the H.STAT control so that
the Red, Green and Blue points are on top of each other at
the centre of the screen.
2.
[Moving vertically], adjust the V.STAT magnet so that the
Red, Green and Blue points are on top of each other at the
centre of the screen.
3.
If the H.STAT variable resistor is unable to bring the Red,
Green and Blue points together at the centre of the screen,
adjust the horizontal convergence with the H.STAT variable
resistor and the V.STAT magnet in the manner indicated
below.
[In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other].
The movement of the magnets interact with each other and so
the respective dot position should be monitored while carrying
out this adjustment.
Use the H.STAT VR to adjust the Red, Green and Blue dots so
that they coincide at the centre of the screen
(by moving the dots in the horizontal direction).

If you are unable to adjust the corner convergence properly,
this can be corrected with the use of permalloy magnets.
HTIL correction can be performed by adding a TLH correction
assembly to the Deflection yoke.

Preparation:
Before starting this adjustment, adjust the horizontal and
vertical static convergence.
1.
Remove the deflection yoke spacer.
2.
Tilt the deflection yoke as indicated in the figure below and
optimise the geometry.
Tilting the DY Up and Down will balance the upper and
lower pin adjustment.
Tilting the DY Left and Right will balance the H-Trap
adjustment.

Initialising Menu
The menu contains a list with all the available models of this
software to set up the TV set in an easy way. The selection
of a model is setting data for its features and hardware
resources which cannot be detected by the automatic power
on H/W detection as well as a special model byte to get an
unique model identification for models which cannot be
differed by features and hardware resources
(e.g. KD-32DX100U and KD-32NX100U).
Before data is set, the user will be asked if he really wants to
set a new model. If the user agrees, the destination setting
menu is automatically shown.
