The azimuth adjustment keys don't work

Send it back along with the hand controller describing the problem. Could be several things including a bad hand controller. If there is a local astronomy shop nearby take the scope there and ask to try one of the hand controllers in the shop and test it. If it now works you just need to buy another hand controller.Otherwise send it in for repair

ETX125 PE new model. Elevation has totally stopped.

Could be that the DEC motor driver has died. That could be verified by swapping the connections between the RA and DEC. If the DEC now moves, then that is the problem. If not, then the DEC motor is bad.

Hi I have a meade ETX 105 pe I can get the scope to move Alt motion with the controller but it wont move in the Azimuth position with the controller. Might I be doing something wrong

This can be caused by 4 things-A stuck button on the hand controller.A bad hand controller cableA burned out circuit board insideA burned out Azimuth motor(Long shot) bad firmware in the hand controller. DO a Reset and reload the firmware.Try to borrow another hand controller and buy a new cable. If these two do not fix it then it's a mechanical problem or a circuit board problem inside the scope. Meade can repair this but you will need to send them the scope:
