( Note: The above specifications are suitable for most of the TV models, and for your reference only.)

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 LCD 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 LCD 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.

Attention:

2.5

LVDSVDD – if the LCD is in 5V, it must be switched to the setting of 5V. And

if the LCD is in

12V, it must be switched to the setting of 12V. (Switch setting: CN3 -- 5V or

12V )

3. Instruments

Max Input Current : over 1A / Max Input Voltage : 500Vdc Measurement Range : 10Mvr~100Vdc / Accuracy : 0.03%

3.2 Oscillograph

Frequency Band : over 20M /Input Impedance : over 1M Input Capacitance : below 30pF / Max Input Voltage : 250V

3.3 PC: XGA (1024X768@60Hz)

3.4 HD Singal Generator: 480P 576P 720P 1080i@50/60HZ

3.5 DVD Player: Audio/Video output, S-VIDEO output, HDMI output.

3.6 VGA cable, S-VIDEOcable, RCA cable, YpbPr cable and HDMI cable.

4. Software Upgrade

The chip inside the LCD 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.
