I'm new to this but have just changed over my old black lab 4000's for silver ones i correctly transfered them and rewired connecting to my beolink pc2 but when i attempt to play music i turn them up and hear nothing but fuzz is there anything anyone can advise me to do ?
Cheers

First very silly thought, and I apologise for this - you have switched them on? The button on the front?

Second, have you tried using them with another piece of kit? The PC2 can not work for all sorts of reasons so I would want to make sure it was the speakers first! Try switching everything off, make sure all the connections are made, and then re-introduce the power.

The buttons don't actually switch my BL4000 off! When i turn them on and off... well they don't turn on and off! No difference except for the pretty little lights being lit.

When the music system is in standby, there is white noise from the spekears with the buttons off. When i 'turn them on', the noise is gone. When the music is playing, turning on and off the buttons makes no difference at all. 

 Are my BL4000 dodgy? Or is the button just a pointless feature...
