Surface Pro 3 touchscreen jumps to one specific pixel every few seconds
Surface Pro 3 fully updated.
Every few seconds, say about 10 seconds, the mouse pointer jumps to one specific pixel when I'm in the middle of working, which takes the focus away from what I'm doing. I know it's a specific pixel because, when this happens, the faded grey circle (like when someone uses touchscreen) is shown on that pixel. Interestingly, the pixel has the same aspect ratio as the screen itself - it's two-thirds of the way across the screen, and two-thirds of the way up as well. I've tried calibrating the screen but no joy.
This is so annoying that I've had to disable the 'HID-compliant touch screen' device in Device Manager, but of course this just switches off the touch-screen entirely.
This first happened a few months ago, and I hoped that it would get fixed in a future Windows 10 cumulative update or future update. It's had both of these but the problem remains so far.
Any ideas?

that's how you troubleshoot it imo

That's more of a troublenuke than a troubleshoot ;)
You could try cleaning the affected area with dilute acid such as watered down vinegar but it does sound like a hardware fault.
your choice to take it or not

Discovered that the fault is more than I first thought. There is a band on the screen where the touch doesn't work at all. Went into bios to check, and the issue is there too. This is one of the troubleshooting steps I was looking for. The other is the Surface Diagnostic Toolkit https://support.microsoft.com/en-us/help/4037239 which made the extent of the problem more apparent

As for the reset to factory settings option, this would be my last resort, but before that I was hoping to get some ideas about how to troubleshoot this really.
