Re: LX200 EMC MEADE 8 INCH
By doing this trick--
Do a FAKE alignment-- (I assume that the scope is trained and has the proper date, time, and site)-- just push the buttons for the alignment stars that you cannot see. Then do a GOTO to a star that is in your field of view--- center the star and SYNC. Your gotos will now be OK in your limited field of view.
Alinealo primero con la estrella polar, y despues con aldebaran que es la estrella mas brillante del cielo. Utiliza el buscador que es el telescopio chiquito que tiene en un costado. pero mejor ve a un curso. bye

This model LX200 classic has weak capacitors that blow out with age. Go to the Yahoo LX200 group-- post a message with the problem for "Ron Sampson" he can repair the board if it is broken. Also Dr. Clay and Andrew also post to this web site--- they know a lot about LX200 electronics.
I have a LX200 EMC 10". I had a similar software problem and solved it by downloading AstroFinder, bypassed the onboard software of the telescope, and controlled the telescope via my laptop. This was a more user frriendly method and allowed easy alignment of the telescope.
You have a LARGE Meade telescope. This should be an easy fix if you can disassemble the fork arm and get inside.
First I would contact Meade customer service to see if they have a manual that shows disassemble instructions. If not I would join the Yahoo LX200 forum and look for help there with an owner of the 16 inch model.
Just search in Yahoo Groups for the LX200 forum.
On smaller scopes the DEC motor is held on by two spring loaded bolts, probably one has become loose?
This makes sure that the scope is calibrated properly.
Do an AUTOMATIC ALIGN
when asked to center star, look for the BRIGHTEST star that is close to the scopes field of view. It will be that star you need to used the arrow keys on to centre it in the scope eyepiece and press enter.
This star can be as much as a HANDS distance away from the centre of view
If you cannot identify the star it is asking you to use, press the SCROLL DOWN key to choose another star, keep doing this until you see a star you recognise.
You can also hold down the MODE key for about 4 seconds and scroll through the scope info. Make sure you have the correct location coordinates ( Lat/Long) and the correct time set.
Select a bright object first such as a planet and GOTO it. Once you have manually centered it in the eyepiece, press ENTER and hold it for 6 seconds, the handset will say " Press ENTER to sync", press enter and you have updated the scope with the coordinates of that object.
Most problems tend to be mechanical. Have you 'trained' the drive and set the backlash values? Those 2 can have dramatic effects on pointing accuracy. Also, if the optical tube is not in alignment with the mount, then nothing will work correctly. To check that, have the telescope in Alt-Az configuration, inside the house, loosen the RA lock, and shine a laser pointer on the corrector plate. as the telescope is rotated about the RA, the reflected spot should be steady. Adjust the DEC to minimize the diameter of the circle that is drawn. What is left, is the out-of-true on the DEC axis. That can be adjusted with the tube cradle alignment bolts.
