Note 1:

POW/DEF board: P451/

M450

Horizontal screen

positional switch

Screen position shall be

switched by inserting a

plug into the above pin.

(CENT should take the

first stage)

Horizontal adjustment shall be made using E-12CH Philips pattern and DYNAMIC

image mode.

1) Using WID data, reduce the horizontal amplitude until a part of it is dropped out.

2) Using WID data, adjust the horizontal amplitude so that horizontal raster inevitably

contacts with CPT mask.

3) Using the following (Note 1) horizontal screen positional switch, adjust the horizontal

raster position to the center position.

4) Using the horizontal amplitude

(WID) and horizontal phase

(HPOS), adjust the horizontal

amplitude so that the right and left

flags are just blinded.

The adjustment shall be made so that the right and left flags are just blinded.

5) Using PARA, TRAP, CNR and CPAR (or TCNR, BCNR or CSAW if necessary),

adjust the screen distortion.

6) If necessary, make the horizontal amplitude adjustment again.

For NTSC WIDE

Horizontal phase

Horizontal amplitude

(NWID)

Side pin distortion

(NPAR)

Trapezoidal distortion

(NTRA)

Corner distortion

(NCNR)

CENT distortion

(NCPAR)

Parallelogrammatic

distortion (NCSAW)

Upper corner distortion

* NTSC adjustment shall be made after PAL adjustment.

1) With domestic 13ch, WIDE

mode and DYNAMIC, adjust

the right and left bars to the

fifth center for horizontal phase

(NHPO)

and

horizontal

amplitude (NWID).

Right and left bars shall be adjusted

to the fifth center.

2) With domestic 11ch, NPAR, NTRA, NCNR and NCPAR (or NTCNR, NBCNR or

NCSAW if necessary), adjust the screen distortion.

3) If necessary, make horizontal amplitude adjustment again.
