Huion 16(21) black screen even though driver sees it and the pen works!

Hello, I ve ordered HUION Camvas 16(21) 15.12.21 Since yesterday I can't turn it on. I mean, I ve tried it on different devices (PC, laptop) and both of them can see it, the pen is working too(I mean I can see the movement of the coursor on my laptop screen), but the screen of the tablet itself remains black. I've reinstalled drivers a few times, restarted everything a few times (with and without tablet unpluged). I've also tried connecting my usb in different ports, as well as using black, red and flat one at a time, I tried connecting red usb to the power adapter. Nothing works for me. I can't see what the problem is, because everything worked perfectly fine for 3+ weeks.
