I’ve had a surface pro 3 for a long time and it has generally been amazing. But, twice now, I have had to go through an issue where a few parts of the screen totally stop responding.
It happened a year apart or more and I forgot the solution originally, so I’m posting it here!

You run that sony app, it calibrates in CLI for a minute, then open up your windows 10 touch screen callibrator (you can find that by searching for “touch screen” on your search bar on by the windows logo). Run that, and you should be good!
Coding Stream of Consciousness 
For anyone finding this, here is what I did.
1st, contrary to what many might believe this IS NOT a hardware failure. It is a common issue with this Sony touch screen on the surface products (all of them it seems).
2nd, the clibration utilities everyone posts, even the Sony one did not work. For me the sony one would not even run on my Windows 10.
What I did:
As I had intended to install Lunix on this Surface because of the impending end of WIndows 10 (no, I do not want 11 even though I can through my companies MS licenses), So I installed Fedora KDE Mobile and the broken touch was a real issue. So I reloaded WIndows 10 and tried the sony calibration utiliuty, it failed. So then I installed several sessions of updates rebooting each time.
Initial re-install of WIndows 10: Touch screen still broken. Calibration tool doesn’t work.
1st updates: Entire touch screen stopped working. Calibration tool doesn’t work.
2nd updates: Entire touch screen starts working fine, no dead spots!
I then proceeded to install Fedora KDE (I installed the desktop version this time and then installed Mobile as a secondary desktop so I can switch between them) Touch screen fully functional!
Conclusion:Even though my original Windows 10 was up to date it did not fix the touch screen. I believe that the 2nd set of updates on the fresh install did a remove and re-install of the touch screen driver that re-initialized the screens calibration data. Wiping out what ever was broken. If you don’t want to re-install you may want to try removing the device from Device Manager and let it re-find and update the driver but I doubt that will work. I am not sure how you would fully ininstall the driver without a reload.
Notes on re-install:
I was never able to get any new OS, neither Windows nor Linux to install with secure boot enabled. So if you are going this route, you will need to disable secure boot. While there are ways to install keys and then enable secure boot after your OS install I just didn’t bother as it is not that importabnt to me on this device.
