Backlight, power, volume, home button, and touch working but no image

Hello,

I have an iPad Pro 10.5 64GB WiFi+Cellular (A1709) from a friend at home.

He told me after the iOS 13.2 update his screen quit working.

He mainly uses the iPad with an HDMI adapter and he says its displaying just fine on the TV, but nothing on the iPad itself.

So I allready tried the following:

- Checked that all buttons work (with “Realtime Screen” from “3utools”) - all of them do what they are supposed to

- Battery is charging just fine 84% as we speak

- Displaying the image on the computer again with “Realtime Screen” from “3utools” - works great

- Backlight goes (quite dimmly though) on when starting the iPad, and off when clicking the power button

- Tried twice to reset the device with home button + power for around 30 sec, the iPad seems to restart as you can see the backlight going off and after a short while on again

Would you open the device and try with a know good screen, or would you try to install another version of iOS or maybe other suggestions.

Thank you for your time!"
