( regardless of channel.)
b. If you press IN-START -> ADJUST , the LINE SVC mode
changes to screen adjustment mode.
c. Turn the Screen volume of FBT until the horizontal line is no
longer seen and then stop.
d. Press the EXIT button to exit Screen Adjust mode.
3.3.2 White Balance Adjustment
Prior to this adjustment, screen voltage adjustment must be finished.
1). Necessary Instrument
(a). White Pattern Generator (Can generate Low/High Light pattern)
(b). White Balance meter( CRT color Analyzer,CA-100)
(c). Factory Remote controller
2) Preliminary steps
(a). Tune the TV set to receive an 100% white pattern.
(b). Perform screen adjustment first.
3) Adjustment
(a). Enter into adjustment mode by "INSTART" key and
select SERVICE1 mode.
(b). Adjust the item with CH+/- Key.
(c). Adjust the data with VOL+/- Key.
(d). Adjustment Procedure

If Line is not for LG TV SET, receive the avalible Pattern to adjust
Deflection.(Ex : Cros Circle)
3.4.2. Adjustment.
1. Deflection Data Adjustment should be follow below sequence.
a. Adjust at N50HZ(PAL) => N60Hz(NTSC) => Z60Hz => N50HZ
=> W50Hz => Z50Hz
b. This sequence is only for specific model which as a ARC
function.
Note : If adjust at N60Hz, every data will be changed to revised
data automatically compared with N60Hz
2. In case of NTSC only model, adjust deflection at 60Hz of NTSC
signal.
