how to usb updating firmware LED,LCD TV Universal Main Board

step 1: Empty the pen disk.
Step 2: Copy the corresponding resolution program (*. Bin file) with the TXT file to U disk.
Step 3: Connect the U disk and TV Mainboard Via USB Interface.
Step 4: Connect the Keyboard and TV Mainboard.
Step 5: Connect power supply, check keyboard light. If light flashes, means firmware is being written; until light turns to Green, work is done.
(If light is not flashing, please cut off the power supply, then reconnect the USB, then connect the power supply again).

(Note: *During Step 5, the power supply can’t be paused* The same firmware can only be burned once time) After all done, use the remote control to turn on the tv (after burning the firmware, the mainbaord is on standby, the remote can wake up the tv)
