Do u do cable repair/replacement?? I got an old logitech z640 5.1 system... the main cable (i.e. the cable connecting the subwoofer and the pc) has been cut. Brought it to an av specialist last time, he soldered the cables back, but no joy... the speakers still don't work... If possible, prefer medium grade cable, not high end cuz it's just a low-end speaker...

If possible, please PM me, thanks!
