SAFETY PRECAUTIONS IMPORTANT SAFETY NOTICE 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 Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.

General Guidance An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation. If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified. When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1 W), keep the resistor 10 mm away from PCB.

Do not use a line Isolation Transformer during this check. Connect 1.5 K / 10 watt resistor in parallel with a 0.15 uF capacitor between a known good earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which is corresponds to 0.5 mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.

Leakage Current Hot Check circuit Keep wires away from high voltage or high temperature parts.

AC Volt-meter

Before returning the receiver to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, etc., to be sure the set is safe to operate without damage of electrical shock.

Leakage Current Cold Check(Antenna Cold Check) With the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs. Place the AC switch in the on position, connect one lead of ohm-meter to the AC plug prongs tied together and touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, the measured resistance should be between 1 MΩ and 5.2 MΩ. When the exposed metal has no return path to the chassis the reading must be infinite. An other abnormality exists that must be corrected before the receiver is returned to the customer.

A PC or a MNT will display an optimal resolution through information sharing without any necessity of user input. It is a realization of “Plug and Play”.

3.4. Model name & serial number download (1) Model name & Serial number D/L A Press “Power on” key of service remote control.(Baud rate : 115200 bps) A Connect RS232 Signal Cable to RS-232 Jack. A Write Serial number by use RS-232. A Must check the serial number at Instart menu. (2) Method & notice A. Serial number D/L is using of scan equipment. B. Setting of scan equipment operated by Manufacturing Technology Group. C. Serial number D/L must be conformed when it is produced in production line, because serial number D/L is mandatory by D-book 4.0

(2) Equipment - Adjust remote control - Since embedded EDID data is used, EDID download JIG, HDMI cable and D-sub cable are not need. (3)Download method 1) Press Adj. key on the Adj. R/C, then select “12.EDID D/L”, By pressing Enter key, enter EDID D/L menu. 2) Select [Start] button by pressing Enter key, HDMI1/ HDMI2/ HDMI3/ RGB are Writing and display OK or NG.

5. Tool Option selection - Method : Press Adj. key on the Adj. Remote Control, then select Tool option.

6. Ship-out mode check(In-stop) After final inspection, press IN-STOP key of the Adj. R/C and check that the unit goes to Stand-by mode.

7. GND and Internal Pressure check 7.1. Method 1) GND & Internal Pressure auto-check preparation - Check that Power Cord is fully inserted to the SET. (If loose, re-insert) 2) Perform GND & Internal Pressure auto-check - 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.

4.3. EYE-Q function check Step 1) Turn on TV Step 2) Press EYE key of Adj. R/C Step 3) Cover the Eye Q II sensor on the front of the using your hand and wait for 6 seconds Step 4) Confirm that R/G/B value is lower than 10 of the “Raw Data (Sensor data, Back light)”. If after 6 seconds, R/G/B value is not lower than 10, replace Eye Q II sensor. Step 5) Remove your hand from the Eye Q II sensor and wait for 6 seconds. Step 6) Confirm that “ok” pop up. If change is not seen, replace Eye Q II sensor.

8. USB S/W download(option, 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 High, USB data is automatically detecting 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” button. 3) Push in the number. (Each model has their number.)
