Looks like a software error to start with. My initial suggestion would be to contact Burny support. Lincoln owns Burny now and I suspect they have decent telephone tech support. Next - what do your schematics say about power to the lower panel? Could be just a loose connection/blown/missing fuse or it may not be enabled until the control boots up completely.
Lastly, if you have decent computer/electrical/electronic skills then have at it yourself, however, if you don't, you may want to get a professional involved
