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.
