Was working, now touch blinking when Autohome

Howdy, just picked this unit up a couple of days ago and got everything up and running without incident for the two test files, plus a couple more from Thingaverse.

This morning I kicked off a print and had to abort as the filament was not feeding properly. I got that issue solved, but now the touch blinks red when trying to Autohome. Works fine to auto level but fails in the second Autohome and when trying Autohome only.

I have reset the parameters and redone manual level, but didn’t help. Unplugged and reseated the cable connectors.

Firmware from the Info screen shows 1.1.8c, but I don’t see any other firmware versions to make sure I have all of them up to date.

Any thoughts?
