I have a problem with all three of my controllers that when they are not connected to the xbox, but the xbox is on, they can not connect to the xbox. Some examples of this for me are:
I turn my xbox on through my controller ( so both are on ) and then I leave my xbox alone for a while so the controller turns itself off to conserve battery power,
I turn my xbox on through the xbox button ( so only xbox is on ) then the controllers can not connect to the xbox.
The controller can not connect back to my xbox or I have to get fresh batteries for my controller, it will not connect back to my xbox when I put the new batteries in.
When I sync my controller, the controller blinks like it synced, but it will not turn itself on and keep on blinking.
** When trying to connect my controller to my xbox it just blinks like it is not synced to it, yet trust me, it is. Sometimes the controller actually does connect back to the xbox, but 90% of the time it does not. I do not know if my headset can help find the problem, but if I unplug my headset from the controller, only half of the time the xbox recognizes the headset is actually in the controller meaning sometimes I have to turn my xbox off so I can talk and hear people through my headset again. I have the new xbox 360 250GB Kinect Ready Version and this has been happening for a while now. I am finally put up with it, and was hoping that someone on the forums could answer my question. I am xbox inclined so please do not give me "Try syncing it" response, because trust me, I have tried all I can do.
