Chuwi HiPad Pro white screen help

Good afternoon. Can anyone give me some help? My Chuwi HiPad Pro was on and working normally, I went to sleep. When I turned it on, the screen is all white (but it turns on normally) as if the LCD had burned. But it makes no sense because when I turned it off there was an image, it didn’t fall or anything. Has anyone had this problem? Can you help me tidy it up? I thank the attention.

@Debora I guess your Hipad Pro is MTK, right? Try boot to bootloader or recovery and factory reset your device. It would be much helpful if you could capture VDO and show what’s going.
