Firmware Instruction

Note: Because the process of the LE46H057 updating is the same as the LE42H057’s, so take the LE42H057 for example:

Ready for F/W Upgrade.

Change the FW “.img1” file name to” safe-kernel.img1” and “.tgz” file name to “update_demo.tgz”.

Example:

Prepare a USB memory (The file system of USB memory must be FAT16 or FAT 32).

* Copy the files (asafe-kernel.img1 & updte_demo.tgz) from your computer to the USB memory, and remove it from computer’s USB port.

Note the version of this F/W is L42.01before you change the software files name.

The software files name must be changed, or TV can’t detect the F/W.

# AC on.

# Plug the USB memory on the USB port on the left side I/O port of TV.

# Press the power key on the Remote Control or the right side of TV to turn on TV.

When the TV detects the USB memory, the LED light is blue and flickers.

For a moment the LED light becomes red and flickers which represents the TV is updating.

The update is ok until the LED becomes blue again.

Unplug U-disk from TV and restart TV.

Check the F/W version and reset to default.

Turn on the TV, press the “MENU” button on the remote control, and then press the number key 1 > 9 > 9 > 9.

You will enter into the factory mode.

Check the F/W version on the second row of the factory mode info (e.g.: the “Ver.” info is V42.01). If F/W version is incorrect, please re-update FW, else turn off BURN IN and do EEPROM initialize.

Do the following steps rapidly:

* Press the “MENU”

** Press the number key ”1”+”9” +”9” +”9”

If BURN IN is ON, turn it off.

After updating, do EEPROM initialize by selecting the “EEPROM INT” and pressing “OK” to start as figure.
