I am new to this site.
I have questions about 2 meade telescopes that aren't fully functional at my school.
I have 2 donated telescopes. One is a meade lx 200 gps10" telescope. We had to do repairs several years ago because the RA gears were jammed. Unfortunately at my school there isn't a good place for storage and I believe the gears were jammed because we carried it too much. We fixed it, we are amateurs, and again this fall we mounted it onto a cart and the RA motion makes a grinding sound. The second is a 8# EMC meade classic. The power works. It seems the controller doesn't warm up to the point of sending instructions. It just lights up and says MEADE. When the power is turned on recently, the scope twirls around.
I am wondering if you had any ideas. One is to find a new mount for the gps scope, one that works, and find someone that knows more about the EMC. We are in Medford Oregon. Any suggestions?
Since you have 2 different versions of the LX200, it is best to have two different threads to prevent any confusion between the two as they are both different. The EMC is the LX200 Classic that is different than the GPS model, and unfortunately Meade isn't capable of repairing the "Classic" model anymore. If the hand controller is stuck at MEADE on the display, the computer is finding a fault during it's boot-up. Does the RA motor run when you first power it on? It should as the computer does a "check" to seek the sensor on the worm gear. If it doesn't "see" the gear is rotating, it stops there. Now that isn't the only thing that causes it to get "stuck, bit it is a place to start. Also, make sure the cables are firmly plugged in and "click" in. Look inside the plugs to see if there is anything in there preventing the cable plugs from making contact with the socket contacts.
There could be just some "dirt" blocking the sensor on the RA worm gear, or dirty/corroded contacts on the cables, or in the sockets. I re-read your message and the RA motor is turning upon power it on?
