Celestron Nexstar 130 SLT motor problem

Hi,

I bought the Nexstar 130 SLT last year and I am now having trouble.

The problem is that when pressing the up and down directional buttons
on the hand control, the motor either doesn't move at all, or moves
only very slightly and sporadic. It is also much louder than before.

Altitude slewing is perfect, very fast.

Is there any way to solve this or does this need to be returned for
repair?

If you aren't comfortable taking it apart to find the problem, or it is
on warranty, by all means return it for competent fixing.
