ESD PRECAUTIONS

Electrostatically Sensitive Devices (ESD)Some semiconductor (solid state) devices can be damaged easily by static electricity. Such componentscommonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integratedcircuits and some field-effect transistors and semiconductor chip components. The following techniques shouldbe used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain offany electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear acommercially available discharging wrist strap device, which should be removed for potential shock reasonsprior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges sufficient to damage ESD devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESDdevices.

6. Do not remove a replacement ESD device from its protective package until immediately before you areready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together byconductive foam, aluminum foil or comparable conductive materials).

7. Immediately before removing the protective material from the leads of a replacement ESD device, touch theprotective material to the chassis or circuit assembly into which the device will by installed.

CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL OTHER SAFETY PRECAUTIONS.

8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motionsuch as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ESD device).

CAUTION. GRAPHIC SYMBOLS

THE LIGHTNING FLASH WITH APROWHEAD SYMBOL. WITHIN AN EQUILATERAL TRIANGLE, IS INTENDED TO ALERT THE SERVICE PERSONNEL TO THE PRESENCE OF UNINSULATED “DANGEROUS VOLTAGE” THAT MAY BE OF SUFFICIENT MAGNITUDE TO CONSTITUTE A RISK OF ELECTRIC SHOCK.

1. To update the Firmware1) Copy the fi rmware upgrade fi le to a empty USB device. Make sure the USB device is empty before transferring the fi rmware upgrade fi le.

2) Hold the Volume(+) key on the remote control unit for 3 seconds, while pushing the Volume(-) button on the main unit. Then, the mode will be changed to the USB update mode. (see 3). (Do not need to change the input function on the main unit)

3) When the USB upgrade mode is ready, all the 4 function LED lamps will be on.

4) Plug the USB device into the USB port on the back side of the main unit. The update process will be started automatically. (The unit will automatically reads the fi le from the USB device) The progress will be displayed sequentially on 4 LED lamps on the main unit. (See the picture of 3)

5) Complete the fi rmware update. When the update is successfully completed, the unit goes into the standby mode after the automatic reset. When the unit goes into the standby mode, the red LED lamp will be on. (Will take about 2 minutes)

2. Urgent Firmware update description If the function LED lamps are sequentially lighting for more than 3 minutes, unplug the power. After waiting all the lamps go off, plug the power again, and then, the Urgent fi rmware update function will automatically restart the update. After the process will be the same with 4 above. (The USB device should be remained on the USB port)

3. How to check the fi rmware version If the main unit is on the stand-by mode, put the pow-er on with the power button. Hold the "standard" key on the remote controller for 3 seconds while holding the Volume(-) button on the main unit. Then, the main unit mode will be changed into the version-check mode, and can listen the current version information.The new fi rmware version is "201512222." If the fi rmware version was updated, the main unit will say D1512222. (20 is omitted, and the letter "D", meaning of DSP fi rmware) Push the "Standard" key once more when escaping from the version-check mode.

3-1. ADC (IC921)3-1-1. SolutionReplace IC921, PN506 on MAIN board.

3-1-2. How to troubleshoot (Countermeasure)1) Please check 5.0 V of IC921 pin3. If 5.0 V voltage doesn’t come out, Replace IC605.2) Please check 3.3 V of IC921 pin4. If 3.3 V voltage doesn’t come out, Replace IC602.3) Please check analog input signal of PN506 pin4, 6. If signal doesn’t come out, Replace PN506 & JK552.

WarningParts that are shaded are critical withrespect to risk of fire or electrical shock.

CIRCUIT DIAGRAMS 1. SMPS CIRCUIT DIAGRAM

WHEN SERVICING THIS CHASSIS, UNDER NO CIRCUMSTANCES SHOULD THE ORIGINAL DESIGN BE MODIFIED OR ALTERED WITHOUT PERMISSION FROM THE LG CORPORATION. ALL COMPONENTS SHOULD BE REPLACED ONLY WITH TYPES IDENTICAL TO THOSE IN THE ORIGINAL CIRCUIT. SPECIAL COMPONENTS ARE SHADED

ON THE SCHEMATIC FOR EASY IDENTIFICATION. THIS CIRCUIT DIAGRAM MAY OCCASIONALLY DIFFER FROM THE ACTUAL CIRCUIT USED. THIS WAY, IMPLEMENTATION OF THE LATEST SAFETY AND PERFORMANCE IMPROVEMENT CHANGES INTO THE SET IS NOT DELAYED UNTIL THE NEW SERVICE LITERATURE IS PRINTED.

1. Shaded( ) parts are critical for safety. Replace only with specified part number.

2. Voltages are DC-measured with a digital voltmeter during Play mode.
