Try downgrading and upgrading the firmware.
From the link above, grab version 1.13.2 and the latest 1.14.3. unzip the files and place them on the USB drive. Using the start or file menu, select 1.13.2 and let it run, afterwards turn it off, back on, and then again with 1.14.3.
If you cannot reach the home screen of the touchscreen, turn the machine off, unplug the tool head, and turn the machine back on without a tool head attached and then do the above. Maybe the linear modules have incompatible firmware and just need updating.
