It happened to me when the battery was less than 1% and suddenly turned black despite charging up. I tried the methods about pressing the buttons to no avail. But then suddenly someone called me and the display came back.

[@HcqsUs]

Hi, Alex, I suggest that you try to replace the screen and see whether the problem is fixed, if it's not, then you have to troubleshoot the motherboard

[@khalildioncom]

[@HcqsUs]

Hi, thank you for your comment, our technician suggest you to troubleshoot and measure the diode resistance of the charging dock connector pin and repair accordingly :) cheers
