1. Safety Precaution.
(1) When moving or laying down a LCD Set, please deal with care. Avoid any impact towards the LCD Set.
(2) Do not leave a broken LCD Set on for a long time. To prevent some damages, after check it, make sure to
turn the power (AC) off.
(3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric shock.
(4) When loosening screws, check the connecting position and type of the screw.
Sort out the screws and store them separately, because screws holding PCBs are working as a ground level,
make sure to check if any screw is missing when assembling.
(5) A LCD Set contains different kinds of connector cables.
Before connecting or disconnecting connector cables, check the direction and position of the cable beforehand.
5
(6) When disconnecting connectors unplug the connectors slowly with care.
(7) Connectors are designed so that if the number of pins or the direction does not match, connectors will not
fit. When having problem in plugging the connectors, make sure to check their kind, position, and direction.
6
2. Preliminary Troubleshooting
2-1) LCD TV does not response or remote controller does not work.
① Check the power cord to be plugged.
② Check the battery of the remote controller.
2-2) Sound is discontinuous or broken sometimes.
① Check [SOUND] -> [AVC] is [ON].
② Set the sound into 'Mono'.
③ Ask for the broadcasting station if the RF cable connection has no problem.
④ Ask for the broadcasting station to check signal strength of RF cable.
2-3) Picture of digital program is sometimes broken and sound is discontinuous.
① Digital program has a little problem because of signal receiving status.
② Check the RF cable connection.
③ Ask for the broadcasting station if the RF cable connection has no problem.
④ Ask for the broadcasting station to check signal strength of RF cable.
2-4) Picture of analog program is noisy.
① Check the RF cable connection.
② Check [Picture] -> [Noise Reduction] is ON.
③ Change the [Install] -> [Analog or Digital Manual Tuning] -> [Fine] value.
④ Ask for the broadcasting station to check signal strength of RF cable.
2-5) Sound is not generated in HDMI mode.
① Reconnect HDMI jack.
② DVI cable has no sound. Check the output signal of device to be connected to LCD TV.
③ If you want to use DVI-HDMI cable, to listen sound, stereo cable should be connected to PC audio jack.
2-6) In spite of 'Auto Adjust', picture size in the PC mode is not completely adapted to the screen.
① Check if the input signal is available.
② Ensure that the desktop has no black area.
③ Some errors (picture position problem) will be occurred according to certain video card.
In this case, you should adjust 'Frequency' control.
2-7) In spite of 'Auto Adjust' in the PC mode, picture is not clear.
① Adjust 'Phase' control.

Precautions when using the USB device
• Only a USB storage device is recognizable.
• If the USB storage device is connected through a USB hub, the device is not recognizable.
• A USB storage device using an automatic recognition program may not be recognized.
• A USB storage device which uses its own driver may not be recognized.
• The recognition speed of a USB storage device may depend on each device.
• Please do not turn off the TV or unplug the USB device when the connected USB storage device is working. When such device is suddenly separated or unplugged, the stored files or the USB storage device may be damaged.
• Please do not connect the USB storage device which was artificially maneuvered on the PC. The device may cause the product to malfunction or fail to be played. Never forget to use only a USB storage device which has normal music files or image files.
• Please use only a USB storage device which was formatted as a FAT or NTFS file system provided with the Windows operating system. In case of a storage device formatted as a different utility program which is not supported by Windows, it may not be recognized.
• Please connect power to a USB storage device which requires an external power supply. If not, the device may not be recognized.
• Please connect a USB storage device with cable is offered by USB maker. If connected with cable is not offered by USB maker or an excessively long cable, the device may not be recognized.
• Some USB storage devices may not be supported or operated smoothly.
• File alignment method of USB storage device is similar to Window XP and filename can recognize up to 25 European characters.
• Please backup important files because data on USB device may be damaged. Data management is consumer’s responsibility and as a result, the manufacturer does not cover data damage.

A. Check RC470.
: RC470 is only one path from main chip(IC401) to SMPS. During power on, both sides of RC470 should be
high. If it is high and back light of LCD does not turn on, check as ‘Check followings’. If cables are no problem,
finally check SMPS. (see the page 36)
B. Check RC469
: RC469 is located between main chip(IC401) and transistor(QC701) for switch LCD panel power. During power
on, both sides of RC469 should be high. If it is high and LCD power is low, check as ‘Check followings’. If
QC701, QC702, LC701 are no problem, check LCD panel.
C. Details of Check followings.
-. QC701 : Transistor for switching LCD panel power.
-. QC702 : FET for driving LCD panel power.
-. LC701 : Coil for rectifying LCD panel power.
-. Registers between scaler IC(IC401) and LVDS wafer
