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.

(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.

2. Preliminary Troubleshooting

2-1) LCD TV does not response or remote controller does not work.
Check the power cord to be plugged.
Check the battery of the remote controller.

2-2) Sound is discontinuous or broken sometimes.
Check [SOUND] -> [AVC] is [ON].
Set the sound into 'Mono'.
Ask for the broadcasting station if the RF cable connection has no problem.
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.
Digital program has a little problem because of signal receiving status.
Check the RF cable connection.
Ask for the broadcasting station if the RF cable connection has no problem.
Ask for the broadcasting station to check signal strength of RF cable.

2-4) Picture of analog program is noisy.
Check the RF cable connection.
Check [Picture] -> [Noise Reduction] is ON.
Change the [Install] -> [Analog or Digital Manual Tuning] -> [Fine] value.
Ask for the broadcasting station to check signal strength of RF cable.

2-5) Sound is not generated in HDMI mode.
Reconnect HDMI jack.
DVI cable has no sound. Check the output signal of device to be connected to LCD TV.
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.
Check if the input signal is available.
Ensure that the desktop has no black area.
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.
Adjust 'Phase' control.
