Sorry to hear you've had this whole string of misfortunes with your 'scope. Are you actually saying that it has gone back to Celestron for repairs or that because of the problems you intend to send it back ? Please let us know.
If it's gone back to them no doubt they will sort the matter out but if not, from what I read there are maybe solutions to these problems which the guys here can probably address and solve for you.
Good power supply, for example, is of paramount importance. Without it all manner of ills can and WILL beset the 'scope ! This in turn, may be the source of the altitude axis problem but then again it might just need tightening a tad. How loose does it feel ? Any tendency for the OTA to nose dive if you were to place it at the zenith and then slew it (Mach 9) towards the horizontal taking care of course to catch it should it drop under its own weight.
The clockwise/anticlockwise (counterclockwise) movement appeared to be controlled (or not) as the case may be by the "Cordwrap" feature. With the 'scope aligned, it is "ON".
Ariel seemingly solved his problem by thereafter switching it "OFF". Try perhaps experimenting with it both "ON" and "OFF" a least to establish what happens in both cases.
Hope this helps a little, Best Regards, Tel
