I'm looking for assistance in correcting a problem with my LX90 10". Purchased in 2010, it has been working admirably until recently when it refused to slew down in ALT.
I first thought the problem was with the controller, but after reversing UP/DOWN, it still will not slew down.
Since it is slewing in one direction, I'm assuming the problem is not with the declination drive motor (though I'm not certain this is a valid assumption).
This would leave the motor drive circuit board as the source of the problem... which after contacting Meade support, no longer seems to be replaceable.
So I'm at an impasse and am reaching out to the community for possible solutions.
