Hi, I just registered to this board and I figured this was the best place to post my question. So I've had a logitec x-540 system for over two years now, loved it, was good to me in college and all that jazz. Anyways, I bring it home now that im done with school, hook it up, and the sub doesn't work at all. All the other speakers work fine, and are getting power from the main sub, just there is nothing coming from the sub. I think there might be a problem with a fuse or something because I don't understand how all the other speakers are getting power and signal yet the sub doesn't. So i started trying to take the back panel off, but it will not entirely come out because it seems the power line that feeds into the sub wont budge when u try to remove the back panel. Anyone had any similar problems with trying to repair logitec speakers? I called logitec they couldn't really do anything for me outside of giving me a 50% off coupon, but I'm trying to salvage these guys if i can. I'm really new to the world audio so any input on how i should go about this would help. Thanks in advanced.
