you dont need to program the SPI Flash separate.. just run update or complete firmware again it will write the video & Panel driver again.

Arizan Nothari web page had all what you need.

But dont have any image on LCD...
And also no files needed to update.

Now I do (thanks)....but I will make a backup of both IC´s before usb update.

Take a picture of the tcon/board bonded to the screen.

You may have 12v but let's see what other test points are there. Since you still have sound and the tv functions as normal I'd doubt that the motherboard is faulty at this time.
