Deflection Adjustment

O
1. Preliminary steps
1) NTSC mode should be adjusted after adjusting PAL mode.
2) NTSC adjustment should be done in STANDARD mode of
picture after receiving 13CH signal or MULTI 48CH
signal,and PAL adjustment should be done in STANDARD
mode of picture after receiving EU05 CH.
3) Reset the data in convergence adjustment mode,quit the
mode.
Adjustment Mode : Press the IN_START key and then '0'
key.
Data reset : Press the "0" key.
Adjustment mode cancellation :Press the ENTER key.
4) Display only the Green raster using lens covers to block Red
and Blue.
2. PAL Mode Deflection adjustment
Do not adjust V-LIN, S-COR, A-BOW, A-ANG, UCPIN, LCPIN,
V-ASP, V-SCR in PAL MODE. At SVC mode, press the '0'
key get into the deflection adjustment mode.
1) VS (Vertical Shift)
Adjust until the geometric vertical center line is accord with
the vertical center line of screen JIG in EU 05 CH by
pressing the VOLUME
2) VA (Vertical Amplitude)
Adjust until sixth vertical line from upper and lower center of
the screen is accord with the last point of the frame.
3) HS (Horizontal Shift)
Adjust until the geometric horizontal center line is accord with
the horizontal center line of screen JIG.
4) EW (East-west Width)
Adjust until the outermost left and right vertical line of the
screen is accord with the last point of the frame.
5) EP (East-west Parabola)
Adjust so that middle portion of the outermost left and right
vertical line looks like parallel with vertical lines of the PRT.
