i have a 15 year old (i think, time flies) LX200 GPS. always worked flawlessly until the main control board flaked out. so i ordered a new one from meade and ever since i can not get this to do a proper alignment. first of all it will not keep the date after powering off although other parameters like utc-offset and location are saved. i checked the 2032 battery and its good. I have to enter the current date every time and then the telescope always slews to an alignment star that is below the horizon. if i get it to go to a star that is actually visible and run the alignment routine something is way off because if i tell it to, for example, slew to jupitor it tells me that jupitor rises at some particular time and it wont slew to it even though it is obviousy visible in the sky. HELP!!

1. You shouldn't have to enter the date if the GPS is turned on. Probably time is also off, which is why it is going to the wrong star. Make sure the GPS is turned on.

 

2. If you haven't updated the firmware, there is a GPS bug that makes the system think it is many years off. Update the firmware to the latest 4.2L.

Sounds like the GPS rollover bug. Updating the firmware should fix it. Plan-B; enter the time and date manually.

If you enter your time, date, and timezone manually, please do not forget there is a second timezone setting in the site.  Its easy to miss if you do not scroll past latitude and longitude.

You may need to do an firmware update because of the GPS bug; you will also need to manually update daylight savings time and the UTC offset.
