  • not a solution but you can use scrcpy if you still have black screen even on remote PC then you know it is not a screen problem. but can be still hardware or software error – alecxs Apr 25 '20 at 08:56
  • usb debugging is not activated in my tablet – CiDski Apr 25 '20 at 17:41
  • does it support USB OTG or is it Mediatek Chipset? – alecxs Apr 25 '20 at 20:29
  • yes it supports USB OTG and has an intel cpu . – CiDski Apr 25 '20 at 22:38
  • guess you want recover data? when you can hear sound it may possible to navigate blind with connected keyboard. but you need another tablet for reference https://android.stackexchange.com/q/159551 – alecxs Apr 25 '20 at 23:02
