My wireless controller is starting to break after 3 months of use. Whenever it vibrates, it turns off every second time. Example, when I melee the wall on Halo 3, the guide button light will flicker, as if loosing power, and the controller will switch off. Or when I shoot the battle rifle - the light will flicker three times, then turn off. I checked the batteries, and the battery pack (not rechargeable) is fine, so I figured it is an internal problem. There are some games where you can turn off vibration, but most of the ones I play do not have that option
Any diagnostics, solutions, suggestions?
