Kamvas 22 plus display not working.

The display doesn't even display the no-signal screen. I use a 3in1 cable and checked all of them for damages (there were none). The adapter lights up so it seems to be working, I've tried turning on the second display option in the Windows+P settings. I've reinstalled the drivers completely. Tried plugging it to another laptop and even plugging the adapter in different pockets all around the house. At this point it feels like I've tried everything, please send help the tablet is 3 months old.
