UPDATE:

My ETX came home today and seems to be working.

I did a "dummy" EASY alignment and the motors hummed and the scope went through the motions (although I have had several "Motor Failure" messages. I've done a reset and was immediately greeted by another "Motor Failure" message. Has been OK since.

It even pointed in the general direction of Venus and Mercury when asked to "GoTo", but it was mid-afternoon and I couldn't see the stars!

Typically, it has now clouded over to give 8 octas! Grrr!

Apparently it was a blown motor driver board.
