CR touch blinking red

I have been using my new CR Touch for a week very nicely and all of a sudden it has blinking red.
I have check continuity on the multi color cable.
It will not auto home on the z axis.
Any solutions would be helpful.
thank you!

Same here, had mine for over six months
with no problems - now it randomly works or doesnt. Tried replacing the main lead from the printer to the head - I read they are prone to breaks. the mini cable to the probe is fine - I checked continuity on that. Pin is straight.
