Hello
I'm asking you for help. After trying many things described here without success.

I din't use my Aura (2014) during few months and then it didn't restart.
So what I tried
I plug my aura on wall during a night
When I pushing the starting button the light orange is on and then blinking 10 times.
but screen didn't change. Backlight works
and I cannot see the reader on PC with usb

then I tried the reset button no change
Then I tried factory reset with Light and power manipulation
No change

Then I'm bit stuck
Screen never change.
if the screen is broken I should see the reader on the pc no ?
What can I try more ?

thanks in advance and best wishes for 2018
