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.
Remarks: When the first upgrading is finished, the action of turning on the
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.

9. APPLICATION REQUIREMENT

¾ Relative humidity ≤80%

¾ Store temperature -10~+60 ℃
¾ Use temperature 0~+40 ℃
¾ The procedure of the whole machine assembles and transports need to
attend ESD transaction.
¾ When the whole set assemble, it can down pack or side pack, but don't
make the board transform or distort, don't be subjected to heavy pressure.

W
¾ The hole of each port does not be opened too small, especially the HDMI
port hole, avoid the whole set morphing to cause the extrusion of port when
installing.
¾ The hole of RGB socket is recommended the situation of not using the

IE
screw stationary on the RGB socket to fix on the structure board.
¾ The connected wire which between the other boards and this board can't be
leaded too long, or affect performance and image quality.
¾ The whole set inner wires matching reasonable, each connected wire try to
AV
not directly cross the PCB board, especially cross over from the main IC,
avoid affect the whole set EMC performance.
¾ n order to obtain better EMC effect of the whole set, we suggest the LVDS
twisted pair wire between the main board and panel must be tied up well
and try to use shielding wire. If it’s possible, try to put on the magnetic belt
R
ring on the wire which near the board terminal.
¾ The HDMI and HDCP on the main board are all passed the related
certifications, but we just provide testing certification of the inner usage
LT

standard. If you need to use legal HDMI and HDCP, please apply related
association as formal member by yourself.
¾ There is ROHS identification on the board and package, the board match
ROHS standard.
¾ For Safety Issue, please keep 8.0mm at least from the metal parts of the
U

system to the mainboard(power part). Or, put a mylar between the

mainboard(power part).and the metal parts to avoid the safety issue,.
