I got a buddy who is looking for a sub and he found a DT SC4000 that powers up,but no sound. I asked him if the guy selling it had opened it up to see if anything had blown,etc. and he hasn't. He's selling it for $75,but I'm not sure if he should take a chance on it to see if it's something simple or something major.
I'm not sure of the internals of the SC4000,so I'm not sure what could be wrong with it.So,should he or shouldn't he?Thanks
