Meade LX 200 spins around non-stop when powered up

When I turn on my Meade LX200 the azmuth motor just spins the scope around. The control pad starts to perform POST but then freezes and doesn't respond to inputs. I've tried cables, fuses, and settings to no avail. Please help. I don't want to miss the winter observing season, although the scope still works manually, it isn't the same without the electronics!
Thank You,

    Power cycling doesn't work. Unit doesn't didplay any codes, it only displays MEAD opening screen then goes blank, lit up but no characters displayed. Tried swapping cable, no change. tried with control pad disconnected, no change. I checked and re-seated ICs and checked for corrosion, bad solder joints, nothing found. Unit worked fine one night then displayed the problem the next night when I turned it on it started up OK then started acting crazy.

    Meade LX200 7", 8", 10", and 12" models have been designed and manufactured for years of trouble-free

    operation and repairs should rarely be necessary. If a problem does occur, first write or call our Customer

    Service Department. Do not return the telescope until you have communicated with us in this way, since the

    great majority of the problems can be handled without the return of the telescope to us. However, should the

    occasion arise that the instrument requires factory servicing, a Meade Instruments Customer Service

    Representative will issue a Return Goods Authorization (RGA) number and give you full instructions on how

    to use it. Product returned without the RGA may greatly delay any servicing or repairs. When telephoning or

    writing, please explain the exact nature of the problem so that we may offer a prompt remedial procedure.

    Be sure to include your full name, address, phone and fax numbers where you can be reached.

    Should you live outside of the United States, contact your Authorized Meade Distributor from where you

    purchased the instrument.

    If the telescope parks with the tube away from the normal park position or stops displaying the
    message ‘ park position outside lower limit do the following
    o Turn off the power
    o Wait for a short period and switch it on again
    o Re-start the scope using the procedure in Turning on the telescope
    o Move the telescope to the park position using the hand controls. The tube should be level and
    pointing due South – Due south can be checked by ensuring the RA scale reads zero
    o Park the telescope
    Re-start the scope using the procedure in Turning on the telescope

You have GOOD power? You can try and replace the hand controller cable--

I would also Calibrate motors, and retrain the drives. But re-training must be done in alt az mode.

Is this an LX200 or an LX255 which I have never heard of.

Does the scope focus on a distant object during the day time? If YES nothing is wrong with the scope.

The eyepieces determine what the magnification will be. The eyepiece with the largest number on it is the LOWEST magnification. Meade has a web site with all of their manuals here:

My Meade LX-50 telescope has developed an electrical problem. When I turn it on it immediately blows the fuse. I tried disconnecting the drive motors, and it still blows the fuse, so I think the problem is...

A fellow by the name of Ron Sampson can repair hand controllers and main boards on Meade telescopes. He does very good work. All you need to send him are the board(s).

You can contact him by posting a message on the Yahoo LX90 or LX200 group forums.

Good luck-- by the way he repaired the hand controller for our astronomy clubs 10 inch Meade LX200, at a very reasonable cost.

Meade 14'' LX 200 GPS telescope

If it will not boot-up it's probably the main board. However, I would try a brand new hand controller cable first before I panic.

A fellow by the name of Ron Sampson can repair the hand controller and or the main board circuits. He can be contacted by placing a message for him on the LX200 and the LX90 Yahoo Tech Group.

Hope that helps you. You can send him the hand controller and the main board and he will have a look at it.

Meade LX200 drive system keeps spinning

The older Lx200's go into tracking mode when turned on if they are not recieving a signal from the handbox. It does this on purpose so you can use the telescope without the handbox and still track sky objects. If it is still doing this with the handbox plugged in then you have a bad chip in the electronics and Meade is notorious for not having parts for their older telescopes. Don't send it in to them to repair. It will cost you a fortune to mail back and forth and they still can't repair most electronic problems with their older scopes(from my personal experience).

Problem with start up on telescope

Most probably, flat batteries. Autostars go berserk when batteries are even a little low. Try it with a mains power adaptor instead.

Otherwise, maybe its a dodgy curly cable, broken Autostar, broken control panel or Autostar firmware needs reloaded
