Eric I went back and reviewed your other posts. Have you contacted anyone at an Astronomy Club near you? If not there is a list at:

http://www.astronomyclubs.com/1/190/11/0/club.aspx

This lists all of the Florida Astronomy Clubs. Members of Astronomy Clubs almost always have a member or two that has the talent to assist in finding the problem with your scope. They just need to dig into the scope and find the problem. The ETX scopes are so common, someone in the club is likely to have one that could try their cables and controllers with your scope. It could be a damaged wire or blown circuit board or the like you should be able to trace the problem to and get a replacement item once the problem is narrowed down. Club members would also likely know where to obtain the items without having to deal with Meade directly.
