Thanks for the great suggestion. The Valid Manufacturing tech department was awesome! For future reference, all lights on (including the green light), without a fault light, and all leveling systems working normally points to a problem with the auto-level panel. The tech, Chris, tells me that because of the location of the panel (next to the window) the problem was most likely caused by water getting to the panel. They still make the panel and can overnight it to you for about $400. Thanks again for the great Forum help!!!!
