I am having a problem with my Xbox 360. I press the center button on my controller to turn on my Xbox and it will turn on but no video shows up, the controller won't actually connect, however, I don't get any red rings and my power supply brick remains green while the Xbox is on. I tried searching for an issue but could not find one. (Everything is plugged in and it won't even recognize when I plug in a controller to the USB) It never actually boots. Just turns on. HELP! If it helps, I had to have my Xbox repaired for the red ring of death before.

It sounds like your new controller needs to be "sync'ed" (synchronized) to your console so that the console recognizes the controller. Turn on console with controller. Then press sync button on front of controller (small button) and then within 20 seconds press little sync button on front of controller (not the top, its the forward part facing console, little button)

Connecting a controller to the Xbox 360 is one of those things that should be simple but always ends up confusing and difficult.

Wired is simple; just plug in the controller into a USB slot on the console. It should connect automatically.

For a wireless controller you do the following:
1. Turn on the Xbox 360.
2. Press center Xbox button on 360 controller.
3. Press the small "sync" button on the console.
4. Press the small "sync" button on the controller quickly after step 3.
Of course I never remember the order, so randomly mashing the Xbox button and sync buttons eventually works too. Here's a link to how to sync, but with pictures!

If you're using the Xbox 360 Universal Media remote, I believe it uses an IR (infrared) connection so there is no syncing involved. To use it you just need to point it at the Xbox 360 console (specifically, it's IR receiver). Just make sure the batteries in the remote aren't dead and that the remote is in 360 mode (as opposed to TV mode; just press the "TV" button to toggle modes).

Simply press the big button that has green lights around in front of your console

1. Press and hold the Xbox Guide button until the controller turns on. The Xbox Guide button is the round button with the green "X" near the center of the controller.
2. Make sure that your Xbox 360 console is turned on. If your Xbox 360 console is not turned on, press the power button. The power button is the large round button on your Xbox 360 console.
3. On the Xbox 360 console, press and release the Connect button. The Connect button is the small round button on the Xbox 360 console.
4. On the controller, press and release the Connect button. The Connect button is the small button on the front edge of the controller, between the left bumper button and the charging port.
5. After the Ring of Light spins and flashes one time on the controller and on the console, the controller is connected. The quadrant on the Ring of Light that remains lit indicates the position in which the controller is connected.

• The controller works within 33 feet (10 meters) of your Xbox 360 console. However, objects between the controller and the console may reduce this range.
