2. Maintenance & Safety
2.1 Safety Warning:
(1) The inside key components in the LED must be offered and replaced
by qualified and
appointed manufacturer. Otherwise it may generate electricshocks,
fires or other important unsafety cases.
(2) Don’t try to change the circuits without authorized permission.
(3) Ensure to study the maintenance and service manual thoroughly
before doing any of
the maintaining actions.
2.2 High Voltage Warning:
Please be highly noted the high voltages in the circuit.
2.3 Electricshocks and Fires Warning:
*Connect the insulate transformer between the AC current to the LED
before repairing the panel.
*Take care of the Soldering Pad related to the high voltage circuit. When
there occurs
short-circuit case, please replace the overheated components in time.
*All protective equipments must be re-installed according to the original
design.
*Check the rosin joints, stack welds and the insulations, ensure there is no
objection attached.
2.4 Antistatic Warning:
*The inner circuit boards in the LED TV are sensitive to the statics. Please
take care of the
ESD protection when replace the circuit boards.
*The circuit boards must be packed by antistatic bags.
*Please wear antistatic ring and gloves when during repairing works.
2.5 Attention:
LVDS VDD – if the LED is in 5V, it must be switched to the setting of 5V. And
if the LED is in 12V, it must be switched to the setting of 12V. (Switch setting:
CN9 -- 5V or 12V )

3.6 VGA cable, S-VIDEOcable, RCA cable, YpbPr cable and HDMI cable.
4. Software Upgrade
The chip inside the LED is designed with a FLASH ROM memory program:
it can be erased
and reprogrammed, it can be also updated via the USB port. the program is
related to the chip fucntion ---Different functions of chips need to be planted
with different versions of prgrams.
Please ugrade the new software by the USB port the instruction steps
below:
-------Please copy the new software to the USB
-------Power ON the TV and press MENU to display the main menu ,then
press / to the
OPTION menu. And then select the software in the root of your USB memory ,
Press ENTER .then press to update and to cancel.

tv will be a little slow. So when you turn on the TV at the first time, you need to
press the "power" key on the remote control several times until you turn on
the tv. Turning on the TV at the first time is very important, you need to
operate it carefully to avoid the upgrading is not successful.
