Did you update the 494 controller improperly with 497 controller firmware. You must use this updater software :

Hold down the ENTER key and the scroll down arrow key at the same time abd power on the scope. This will place the hand controller into the SAFE load function and you will be able to do another update.
If you plugged or unplugged the controller cable with the scope turned on you may have burned out the controller. Contact Meade: http://www.meade.com/support/index.html
