So my fiancee and I are sitting here playing zombies on Black Ops and every few minutes either one of our two wireless controllers just shuts off. Batteries are brand new, the battery case is not loose and the springs are getting good contact. Has anybody else had this issue? Could there be something wrong with the sensor that reads the controllers? Is there any way to fix it myself? I am not a lamen with electronics, and I pride myself on being able to fix red rings of death and open tray errors but this is something new to me.
