Sound like either the docking arm or the pwer board, b and w should fix it as there are known problems with the unit, contact the service dept and they should arrange collection. if you have any problems with that, if your model starts z00 or z10 then it has a defective power supply (unless already been for repair) so get it returned because of this known problem. if below z2003 also has the same power problem.
