Kamvas pro 16 black screen

 I've used my kamvas for almost a year, One day I cannot get to turn on the screen: red standby light, pen works fine as I can see in my pc, screen is black.

I already tested in another computer (laptop) with the same result, I checked the FAQs step by step (what to do if the screen is black...blablabla) and it doesn't work.

I've  uninstalled/reinstalled both drivers (graphic card and huion monitor) but nothing changes.

Any help?
