This may mean that the Xbox 360 console you’re using has a hardware failure and may have to be repaired.

To resolve the problem, try the following solutions.

• Solution 1a: Disconnect and reconnect accessories
  1. Turn off the console and unplug its power supply.
  2. Unplug all accessories connected to the front and back of the console, including video cables, network cable, and USB devices. Do not remove the hard drive.

3. Reconnect your console’s power supply, and then turn the console on.
4. Reconnect each accessory one at a time, starting with a controller. Then, turn the console on and check the console power button.
   • If the power button light is green, connect the next accessory.
   • Xbox 360 E or Xbox 360 S console: If the power button light is red after you reconnect a specific accessory, that accessory is faulty and should be replaced.
   • Original Xbox 360 console: If there are flashing red lights around the power button after you reconnect a specific accessory, that accessory is faulty and should be replaced.
5. Repeat step 4 until you have reconnected all accessories.
   • If the power supply light remains green after you have reconnected all accessories, your issue may have been a loose accessory connection.
   • If you cannot determine that a specific accessory caused the problem, there might be a problem with the hard drive, and you may need to remove it from your console.
