This is a summary of a post I did a couple of days ago.
I had the same trouble after polar aligning a new NEQ6 Pro it would not find, track or guide on stars correctly. I used
"Factory Reset" and it now works
I read the manual - no help.
Removed and reloaded all software, upgraded the firmware to 3.25, and stillhad the same problems.
After an all night session and half the next day I rang Bintel and I was told that there was a customer in the store who had had the same problem. I was asked if I had done a
"Factory Reset" - of course not

.
Scrolled through a few menus and found factory reset, which is not listed in the menu tree(manual pg 15).
Powered off/on everything.
Connected to starry night, commenced alignment - alast 100% on target so well I could not find the target star as it was under the cross hair.
Used the Scope live that night and it worked fine.
Hope this will help you.
