Did you buy this from a local authorized Velodyne dealer? If so they should replace it. A good dealer would come to your house to remove the defective unit and install the new one. If a new unit was not readily available, they might even lend you a demo (not necessarily the same make or model) to tide you over until a replacement is available. In my experience it pays to support local dealerships. Hope its taken care of quickily.
Velodyne Subwoofer Problem?
Has anyone else had trouble with Velodynes new subwoofers? I just bought one, HGS-18. It worked the first night, but after being left on all night (it was supposed to automatically shut off), the green light is blinking (which indicates thermal overload). I turned it off and then back on, but it keeps blinking. I think I can smell some toasted electronics. I'd guess something burned up inside.
