LCD Panel Connected but does not work

[maipercaso]

Hi I have recently received my package containing the pine a64 mother board, with lcd display, package is missing the shutdown button, and also the abs case at the Moment.Anyway I received also the 7" LCD Display, I have connected the cables as it was documented in this Forum guide. I did not do any OS upgrade yet, but when I start the os boot up, Display does not light up. I tried to move the ribbon cables attached on the dsi port, and if moved, starts flashing like it was going to start, but then nothing.
I think that the Motherboard or the ribbon cable is defected. Any suggestions?
Thanks

Make sure the cables are set, and do not 'move' them... leave them alone.

The only image that works with the LCD please, is the LCD Android image; try that.
