Is there any green lights coming on, on your 360?

Have you tried using both sync buttons? (one on your controller, one on your 360)

You can try with a plug & play.

this happened to me a few months ago, i dont know if this is the same problem, but i just left it for a few hours and it started working again. hopefully your problem is as simple as mine was

Yeah.. this doesnt happen often but when it does it could be a number of problems.
I know that it could even happen from certain rechargeable batteries. lol

Try restarting your xbox and holding down the sync buttons

Unrecognized peripherals
If your system has had an internal system error (three lights) and is now having issues recognizing controllers, remotes, and/or personal music player’s, the only currently know solution is to rerun initial setup.

Rerun initial setup
Before trying this, it's highly recommend that you remove all hard drive and memory cards. Once you've removed all hard drives and memory cards, navigate to the systems tab in the main menu and select the “Initial Setup” option. Once you select the option, it will ask you if want to run the initial setup that occurred when you first started your console. Say yes and it will do its thing. When it asks for a memory card/hard drive, just decline and it should be done. You should see the default dashboard screen as confirmation that it did, in fact, rerun initial setup.

Resetting to factory defaults / resetting parental locks (unconfirmed)
This was posted on the xbox-scene forums and might work only with older versions of Xbox 360 dashboard.


Press the following key combination


Left Trigger, Right Trigger, X, Y, Left Bumper, Right Bumper, Up, Left Bumper, Left Bumper, X

This should give you a dialogue asking whether or not you want to reset your system to factory default settings.

Reset Xbox 360 video settings
While the Xbox 360 is starting up, hold Y and Right trigger. This will cause the system to reboot and reset the video settings.

P.S i got all this information from wikixbox360.com!
i dont know how this is possible if your controllers dont work i just though of that sorry!
OH and you may need a new rf board.
