I noticed no sound was coming out of my PB1-ISD, so I looked at the back of the sub and the power light was off. I e-mailed SVS, and Tom suggested replacing the fuse. Radio Shack was closed by that point, but I picked up some new fuses this morning. With high hopes, I stuck the new fuse it, plugged the sub in, and hit the power switch: nothing. I pulled the fuse out, and it was blown. I tried a second and third fuse, and the same thing happened. I am very, very upset right now. I love that subwoofer (probably a lot more than my neighbors), but I paid too much money for it to be a loss only 4 months after purchasing it, and the idea of trying to ship that behemoth in for service isn't appealing at all. Has anybody had a similar problem? Any ideas on how this sort of thing is normally resolved?
