I had my LXD-75 for years and the Autostar controller and DEC motor unit failed before, so I ordered the replacement parts.
(Both the DEC motor and autostar. Since the Autostar is discontinued, I ordered the audiostar. You cannot imagine how long it takes to have the parts transfer from China to Hong Kong through the dealer!)
After the replacements, I've found that the DEC motor can move, but no matter the speed i choose from the Audiostar, it spins in max speed.
The RA is working fine at different speed but with DEC moving so fast, it is impossible for me to fine tune the target location in field.
Is that any step I could had missed after replacing the DEC motor? I've calibrated it several time.
Any advise is welcome. I want to use the most out of it instead of just upgrading.
