cambridge soundworks replacement volume control

My question is 'is it possible to retro fit this system with a new volume control cord or a knob type control so that it can work again? By the way, the connection point between the end of the volume control cord and the amplifier plate on the subwoofer is a DIN connection (to make matters even more of a problem). A quick check on Google showed that many tens of thousands of these system were sold and the VOLUME CORD ON ALL OF THEM FAILED!!!! I paid a good amount for this system four years ago as it was touted as THE BEST PC/Media system around.I agree, but I don't agree with Cambridge's/Creative's lousy customer service which effectively said to just throw away the system and buy a new one neither do I accepts its claim to not having the schematics or parts to the system. There is a variable resistor in the volume control head that has failed and without it the the speaker can not be powered up, volume adjusted or balance between left right speakers changed. They claim they don't have the schematics or parts or wiring etc etc.

After contacting Cambridge and Creative (Its parent company) multiple times I have not been able to get a replacement cord or help of any kind from either company on repairing it. I have had it for about four years and have been extremely pleased unfortunately the wired remote control has failed. I have a powered subwoofer made by Cambridge Sound Works(model FPS2000) FPS meaning Four Point Surround Sound.
