How to flash firmware with no picture after replacing TCON board

텍스트:

My LCD TV suddenly stopped showing any picture, not even the on screen menus.  Audio ok, power ok, Backlight working.

# i checked power (12v and 5V) at various places on the 3 boards and its OK
# service manual said tcon board is most likely failure
# installed a new TCON board and downloaded the latest firmware from SOny on usb drive and trying to flash it

I was told to insert the usb drive with TV UNPLUGGED. then PLUG IN TV. firmware should automatically install and indicator light should blink white during the process of perhaps 1/2 hour and then TV would turn on

BUT i dont see indicator light blink. USB stick blinked at first but 45min later, nothing happening.   any help would be appreciated !
