Hi friends. I have a celestron mount Cgem for 10 years. since then it never had any problem, I use it at a fixed location. days ago I went to turn on the assembly and the hand control did not work, after some attempts to turn it on and off, I realized the following: when I turn on the assembly, the hand control indicates "initializing" and quickly goes out, leaving only the bottom of the screen on, but without displaying any indication.
I searched the forum and following some tips, I did several tests:
I changed the power supply, plugged in the auxiliary parallel port and nothing solved the problem. During the tests, I realized that the data transmission function (pressing the INFO AND UNDO buttons) is operational, I updated the latest firmware on the hand control and there was no response. I tried to update the firmware of the stepper motors, but in the software it says that it is not possible to connect the assembly.
The question is to identify which components are defective: the hand control or the MC serial board of the assembly.
Importing these components is very expensive here in Brazil.
does anyone in the group have any idea how to identify the problem?
I appreciate the help.
in time, i'm looking for someone here in Brazil to test the hand controller and sorry for my english, i'm using google translator.
