I have two Autostars with the partially functional displays. An effective workaround is to use the "Hand Control Panel" function in AutoStar Suite. It is found under "Telescope" in the main menu. This acts like a terminal emulator for the Autostar with a display. I can use the keypad on the autostar and the display in Autostar Suite reads correctly. I use a small tablet computer with the Meade interface cable. This is not a perfect fix because it reduces your portability, but it works and confirmed for me that my boxes are functional and that the problem is most likely the display.
One nice extra feature in the AS Suite function, if you have an electronic focuser, is that focus in and focus out buttons are included in the emulator, so you do not have to press and hold the mode button to access the focuser.
Yesterday, I received a new display for the Autostar. Google search "MHS50747-24AG" and you should see this posted in ebay. I ordered two and replaced the displays in both Autostars. They cost $19.99 each. After the installation, both units now work perfectly. The only difference is that the new displays have silver reflective backing, so the display is now black on gray, instead of the nice luminous red in the original. But they fit perfectly and you can still easily read them in the dark. When installing, use your thumbnail to carefully lift the left and right clips holding the display in place. Do not try to pull it out. When you slide the new contact strip in, make sure to re-seat the clamps.
One note of caution: You might be tempted to remove the silver reflective backing. I do not recommend this. The original Meade part has a red/amber translucent glass filter to allow the red LED light to illuminate the letters. I think this may be a polarizing filter. So if you remove the silver reflective tape from the new unit, you will not see the letters when installed.
