Squarewave 200 VRD light stuck on.

admin

Hi all.I have a Lincoln squarewave 200 that I was using welding aluminum.  I welded intermittently with it for about an hour.  Not at all close to the limit.I turned the machine off to cut out some more material.  When I turned the machine back on, the only thing on was the cooling fan and the white VRD light.Display and all controls where off.    I trouble shot everything listed in the owner's manual nothing helps.  Any suggestions welcomed.TIA
