Please don't double post :non: Often it is the fuse on the inverter that goes faulty if you are lucky. The fuse is a tiny grey block that looks much like all of the other surface mounted chips near to it and can often be found by the printing on the PCB saying F1 or similar. A simple check with a continuity tester will tell you if it is OK.
