5.1. Method
- Check that Power Cord is fully inserted to the SET. (If
loose, re-insert)
- Unit fully inserted Power cord, Antenna cable and A/V
arrive to the auto-check process.
- Connect D-terminal to AV JACK TESTER
- Auto CONTROLLER(GWS103-4) ON
- Perform GND TEST
- If NG, Buzzer will sound to inform the operator.
- If OK, changeover to I/P check automatically.
(Remove CORD, A/V form AV JACK BOX.)
- Perform I/P test
- If NG, Buzzer will sound to inform the operator.
- If OK, Good lamp will lit up and the stopper will allow the
pallet to move on to next process.
5.2. Checkpoint
▪ TEST voltage
- GND: 1.5 KV / min at 100 mA
- SIGNAL: 3 KV / min at 100 mA
▪ TEST time: 1 second
▪ TEST POINT
- GND TEST = POWER CORD GND & SIGNAL CABLE
METAL GND
NEUTRAL
▪ LEAKAGE CURRENT: At 0.5 mArms
6. Audio
Measurement condition:
(1) RF input: Mono, 1 KHz sine wave signal, 100 % Modulation
(2) CVBS, Component: 1 KHz sine wave signal 0.5 Vrms
(3) RGB PC: 1 KHz sine wave signal 0.7 Vrms
7. USB S/W download(Service only)
(1) Put the USB Stick to the USB socket.
(2) Automatically detecting update file in USB Stick.
- If your downloaded program version in USB Stick is Low,
it didn't work. But your downloaded version is Higher,
USB data is automatically detecting.(Download Version
High & Power only mode, Set is automatically Download)
(3) Show the message "Copying files from memory".
(4) Updating is starting.
(5) Updating Completed, The TV will restart automatically.
(6) If your TV is turned on, check your updated version and
Tool option. (explain the Tool option, next stage)
* If downloading version is more high than your TV have,
TV can lost all channel data. In this case, you have to
channel recover. if all channel data is cleared, you didn't
have a DTV/ATV test on production line.
* After downloading, have to adjust TOOL OPTION again.
1) Push "IN-START" key in service remote control.
2) Select "Tool Option 1" and push "OK" key.
3) Punch in the number. (Each model has their number.)
No.

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.
IMPORTANT SAFETY NOTICE
THE SYMBOL MARK OF THIS SCHEMETIC DIAGRAM INCORPORATES
SPECIAL FEATURES IMPORTANT FOR PROTECTION FROM X-RADIATION.
FILRE AND ELECTRICAL SHOCK HAZARDS, WHEN SERVICING IF IS
ESSENTIAL THAT ONLY MANUFATURES SPECFIED PARTS BE USED FOR
THE CRITICAL COMPONENTS IN THE SYMBOL MARK OF THE SCHEMETIC.
