Hi all, I've just fixed my controller. you may have had the same problem as me. the button on top wasnt making a connection to the circuit. prise the bass, treble and standby buttons out as one circle from the top of the dial ( i used a thin scalpel blade) basically open it like a mini volcano. Then you'll see the 3 rubber buttons on the circuit. push these with a wooden pencil when its open and all connected up. you may find (without the external button) that it lights up in which case its the lever under the external button thats bent or broken in some way. I hope this helps a few of you. every attempt at replacement parts hit a dead end.

I also have had problems with the Controller, it suddenly stopped working.
After found your note here I pried the top off and voila you are completely
correct. Those contacts, or at least the center small button, dont make
good contact, and without contact no light, no operation. This unit is quite
complex underneath buttons. I was about to give up and chuck it and buy
a Klipsh pc system, but you saved the day with your instruction

once you have the two semi-circle tabs off, it becomes clear the hangup is
the center tiny button. Moving it slightly from side to side for me freed it up
so could turn on and off
