Query: Konk'd out.....

When it worked, this thing was pretty nice. However, i got the same problems as some others. First they said they lost my rebate and there was really no way to contact them. Second, this thing died on me! The main unit doesn't work any more - although the headphone jack still works - that's about it! I'm gonna avoid all yamaha speakers from now on.
