I just recently tried starting up my CEM70 after having had it resting for over a year while I completed my ROR. It seems to be getting power, but only partial. I can see a faint light on the start button, and I can hear faint noise from RA/DEC motor when I push the button on and off, but that's it. No response from HC either. I tested the AC power adapter and HC with my CEM120 and they work fine so its not them. Is there any way to test the board before reaching out to iOptron tech and having to replace?
