i bought the brand new promedia GMX D-5.1 from ebay, usa and had it shipped to melbourne, austrlia. Since the speakers are rated at 120V, i bought a step down transformer to convert the 220V here in australia to use these speakers. The sad part is that every time i turn on power which is located at the back of the subwoofer, the system does not seem to respond at all. The controller also does not work. I have checked the fuse and its perfectly alrite. i have unplugged all the power cables and pluged it well again. But still the system does not work. Could you tell me wether it is the problem with the subwoofer or the controller? If it is the problem with the controller or the subwoofer then can i have it fixed by a good speaker technician? Please help me! im in big trouble. I have been waiting to use these speakers for quite sometime now. And now that i have it, i cant use it. Please advice me what to do!
