Could just be a DEAD battery-- check the manual and replace the battery. If this does not work then it may need to be sent back to Meade for repair:

Why doesn't the GPS pick up a current GPS signal?


You may need to do it outdoors; a building may interrupt enough satellite signal that it (the GPS) won't lock to it (the signal).

If it always says "GPS SIGNAL NOT DETECTED" when it's outdoors, I don't think you're going to get it to ever work. It may have been dropped & the internal antenna damaged.

Gps singal lost


Often, when your GPS is in a "covered" area ... e.g. inside a building, in a tunnel, under a bridge, amongst / under tall buildings, etc... when there is no open space (directly) between your GPS and the satellites, your GPS will loose its satellite signals. If you're in such locations, try to find some "open space" and wait a bit for the signals to be picked up again.
Another common reason why the GPS doesn't get signals, or doesn't get the signals quickly, is because the "latest" satellite positions (locations) have not been updated in your GPS. If/when you connect your GPS to your computer (e.g. using HOME ) and download the GPS satellite (QuickFix) location information, your GPS will have the most recent locations of the satellites in your vicinity/region. With this information, your GPS can pick up the signals more quickly ... instead of having to search/scan around to find the signals ... which can take a bit more time. While your GPS is searching for the satellite signals, it shows the "signal lost" or "no GPS signal" message.

You may have Corrupted firmware in the hand controller- that's why they want you to do a RESET.

You might have to reload the correct firmware to fix this problem.

I believe if you hold down the ENTER KEY and the SCROLL DOWN arrow key and then turn on the scope you enter SAFE LOAD where you can reload the firmware.

Inability for the telescope align


Replace the battery for the GPS.

Start from scratch.

Reset the hand controller, calibrate motors, train drives, calibrate sensors.

Make sure you have either fresh batteries, or better a seperate 12 volt power pack. The above will eleiminate everything except an actual BROKEN electronic part (such as a bad gps board).

If it still will not align using the gps, time to send it back to Meade for repairs. Make sure you have the latest firmware in the hand controller which is 43Eg. You can download the firmware using the UPDATER free software here:

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.
