I've had an AVX mount for about a year and a half and it stopped working in R.A. Since it is still under warranty I contacted Celestron tech support. They paid to have it shipped back to them, replaced the R.A. motor, cleaned and re-greased all the gears, ran a complete suite of tests, and had it back in my hands in 3 weeks.
I have a new Orion Atlas EQ-G mount. I sent an email to their tech support asking about the version of firmware in the H.C. They replied that I should try focusing in the daylight and that should clear up my problem.
Like I said, good on Celestron.
