* Manual Download (Model Name and Serial Number)
If the TV set is downloaded by OTA or Service man, Sometimes
model name or serial number is initialized.(Not always)
There is impossible to download by bar code scan, so It need
Manual download.
1) Press the ‘instart’ key of ADJ remote controller.
2) Go to the menu ‘5.Model Number D/L’ like below photo.
3) Input the Factory model name(ex 42LH4000-ZA) or Serial
model name or serial number is initialized.(Not always)

EXPLODED VIEW
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These
parts are identified by in the Schematic Diagram and EXPLODED VIEW.
It is essential that these special safety parts should be replaced with the same components as
recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
