BLACK screen

Hi guys, i already read about a lot of threads where people are talking about a WHITE screen, but my meizu got a BLACK screen.

i can hear the sound and it obviously turns on and off if i use the power button. also the screen lightens up a bit (hardly visible).

i tried DFU, and i think i used it correctly... still it remains dark.

EDIT: the player doesn't make any noises anymore... is it possible that i have to charge it completely? but even if, previously it was turned on, simply with a black screen.

plz help me

maybe you set the screen brightness to minimum?

hum, no i can't see anything, so i can't turn the brightness lower... additionally.. why should i turn the brightness lower? it would make the screen darker..?

i found some threads about this problem, i'll try the solving possibilities written in there

ok, new problem:
the player isn't recognized by the computer, dfu says "failed to communicate with dfu service" and the meizu DOESN'T START ANYMORE.
theres no sound or short lightning anymore.

wtf is going on xD
