This is my first post on CN and really appreciate all the amazing things I've learned from you all so far here. Last year I purchased a used 2001 model GPS 11" and have loved it! Unfortunately, I think the MC board has failed. When aligning the scope no longer moves left/right and the controller left/right buttons don't respond other than showing the "Rate" number on the display when I press them. I disassembled the scope and swapped the up/down, left/right motor control plugs and up/down buttons do move it right to left so I know the motor is good, but at this point not sure what else to try. I contacted Celestron and they were very helpful, but basically said they can't parts for this old beast anymore and recommended a new mount. I guess my question to you all is is there any other troubleshooting I can do or should I be looking at a new mount? If I'm looking at a new mount, what mount and parts would be needed to make this happen? I saw a few posts similar for an 8" GPS user in a similar situation, but not sure if an Evolution mount could handle the 11" payload. No special accessories mounted at this point, just the scope and finder.
Thanks for any help/input you can offer.
