6.Deflection Data Adjustment (Line SVC-2)
EW (Horizontal Width)
Adjust to that a digital circle pattern looks like exact circle.
NOTE :How to enter into the Line Service Mode with a remocon.
1.Power off.
2.Press the Red button.
3.Press the Green button.
4.Press the Yellow button.
5.Press the Cyan button.
6.Press the OK button.
7.Power On.
6-1. Preparation for Deflection Adjustment
1) At adjustment mode(IN-START button on remote control of
adjustment),changed to LINE SVC 2 mode to adjust the
deflection.
2) Press Channel UP/DOWN button for desirous functionFig. 2
Adjustment.
3) Press Volume UP/DOWN button to adjust the data.
EP (East-west Parabolar)
4) Tune the TV set to receive a Digital pattern.(PAL:05CH)
Adjust so that middle portion of the outermost left and right vertical
NOTE : If production line doesnOt the production line of LGline looks like parallel with vertical lines of the CPT.
TV,receive available deflection adjustment pattern.EC (East-west Coner)
6-2. Adjustment MethodAdjust so that the vertical line at every 4 corners of the screen
looks like parallel with the vertical lines of the CPT.
NOTE : First,adjust deflection at N50Hz,W50Hz,Z50Hz of PAL
signal.Then adjust deflection at N60Hz,W60Hz,Z60Hz ofET (East-west Trapezium)
NTSC signal.Adjust to make the length of top horizontal line same with it of
the bottom horizontal line.
In case of NTSC only model,adjust deflection of
N60Hz,W60Hz,Z60Hz of NTSC signal.
PIP (PIP Position)
Store the deflection adjustment data in EEPROM byAdjust until the distance between PIP and main picture
using ENTER button before adjusting PIP position.becomes about 1~2mm.
1) When adjusting a deflection,adjust N50Hz of PAL signal first and
adjust a deflection at W50Hz,Z50Hz,N60Hz,W60Hz,Z60Hz of PAL
signal.
2) Adjust a deflection as shown below
PAL 4:3=> PAL 16:9=>PAL ZOOM=>NTSC 4:3=>NTSC
16:9=>NTSC ZOOM.
3) After finishing deflection adjustment,press the ENTER button
to enter or exit in SVC mode.
VL (Vertical Linearity)
Adjust so that the boundary line between upper and lower half is in
accord with geometric horizontal center of the CPT.
VA (Vertical Amplitude)
Adjust so that the circle of a digital circle pattern may be
located within the effective screen of the CPT.
SC (Vertical OS� Correction)
Adjust so that all distance between each horizontal lines are to
be the same.
VS (Vertical Shift)
Adjust so that the horizontal center line of a digital circle pattern
is in accord with geometric horizontal center of the CPT.
HS (Horizontal Shift)
Adjust so that the vertical center line of a digital circle pattern is in
accord with geometric vertical center of the CPT.
