Here's some similar stories, including mine. In short, a Windows Update (possibly on the latest Windows 10 build - was for me) appears to brick the touchscreen on at least some Surface Pro 4 devices, but since there's relatively few left about and/or they're all out of warranty, Microsoft seem to be able to ignore the problem their updates caused. https://answers.microsoft.com/en-us/surface/forum/all/surface-pro-4-broken-after-firmware-update/a171195a-a6be-44ca-9bbc-602a8691f507 https://answers.microsoft.com/en-us/surface/forum/all/surfac... https://www.reddit.com/r/Surface/comments/oxg0pm/surface_pro_4_touchscreen_stopped_working_after/ https://www.reddit.com/r/Surface/comments/oxg0pm/surface_pro... https://www.reddit.com/r/Surface/comments/otygmo/surface_pro_4_firmware_failed_to_update_issue/ https://www.reddit.com/r/Surface/comments/otygmo/surface_pro... https://answers.microsoft.com/en-us/surface/forum/all/surface-pro-touch-screen-doesnt-work-after-win10/63f1d8cf-9dde-404d-84fc-9587c991457e?auth=1 https://answers.microsoft.com/en-us/surface/forum/all/surfac... https://answers.microsoft.com/en-us/surface/forum/all/surface-pro-4-touchscreen-not-working/085a2f1b-b176-4ffa-a39c-a5a574864f07?auth=1 https://answers.microsoft.com/en-us/surface/forum/all/surfac... https://www.reddit.com/r/Surface/comments/q8sw6k/comment/hgrli53/ https://www.reddit.com/r/Surface/comments/q8sw6k/comment/hgr...
