Hello all My recently purchased KEF PSW 2000 has given up the ghost, I came back from hols and nothing. I have tried replacing the cable etc but there is no bass coming out at all. The strange thing is there is a signal going to the sub, I have switched the power to auto and the green light comes on. But if I switch the power off there isn't the usual 'thud' you get when you switch off subs Anyone else had anything like this? As i bought it second hand so its not under warrenty. Thanks in advance!
