4.5. Outgoing condition Configuration
- When pressing IN-STOP key by Service remote control, Red
LED are blinked alternatively. And then automatically turn off.
(Must not AC power OFF during blinking)
Confirm whether is normal or not when between power
board’s ac block and GND is impacted on 1.5 kV(dc) or 2.2
kV(dc) for one second

* 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 control.
2) Go to the menu ‘5.Model Number D/L’ like below photo.
3) Input the Factory model name(ex 42LH4000-ZA) or Serial

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.
