Hey guys i have a problem and i seem to be running in to dead ends , me and my son got a celestron nexstar xlt 9.25 carbon fiber used about a year ago it's really nice and we have enjoyed it , i recently went to install a extension from the hc to mount and when i did the hc lost its memory or the boards did . i'm not that tech savvy i had got a used handset and it does same thing shows no response 16 and 17 i removed covers and inspected but see nothing i cleaned pins checked wires and see no faults, i'm lost here and would appreciate any advice or refer me to a repair person or facility it may be over my head to repair it i've never done anything such as this, but willing to try. i think i caused the issue by plugging in the extension a friend made it for us and used cat 5 wire 6 strands i guess that caused it somehow , any advice for old guy here trying spend time with his son would be a lifesaver he keeps getting in and ask if i got it fixed starting make me look bad, lol thanks
