Complete loss of stick forces and joystick does not centre itself like it use to when switched on (everything else on it works including joystick other than it is "floppy" without any resistance from the normal forces that used to be generated by the device). Have reloaded software etc. and tried to run Forces test. Message says "No power" and the red light just in front of stick under M of Microsoft label blinks all the time. Have changed mains plug fuse and also lead but no difference. Think somehting inside the device has failed. Any idea where I can get it fixed?
