you may have a tripped 'buss fuse' or similar named large fuse, probably in the battery compartment, on the wall maybe. This fuse protects the hydraulics that power your levelers. The panel itself runs on 12v and may light up and look operational, but the legs operate on a larger draw, and therefore run thru this 'buss fuse'.
If you see a little 'yellow flag' protruding, push it back in, and then give her another try!
enjoy! : )
