P8 lite touchscreen problem?

I have the old Huawei p8 Lite and don't actually use it very often anymore because it is a second cell phone. Anyway, I want to use it again and I have problems with the touchscreen. I only find videos on YouTube of how others have the same problem. In short, the screen no longer responds, and also not in safe mode. I haven't been to the boat menu yet, but I don't think that will help. Do you know a solution other than swapping the display? The touchscreen only worked properly when I started the device and then it didn't work for the other second.

Did you ever fall for it? I have a Huawei y 635 as a 2 cell phone is very old and it works wonderfully without any problems.

So lately I have not liked the cell phone, so I do not think that any connection has been disconnected.
