Three red lights on an original Xbox 360 console

Three flashing red lights means that the Xbox 360 console or its power supply has a hardware problem. To find out if the problem is with your console or the Xbox 360 power supply, check your power supply light. Here's how:

Unplug and reconnect your power supply. Here's how:

1. Disconnect the power cord from the back of your console.
2. Unplug the power cord from the electrical outlet and the power supply.

3. Reconnect the power cord to the back of your console. Then plug the power cord back into the electrical outlet and the power supply unit.

4. Make sure that all three power supply connections are firmly connected.
5. Turn on your console, and check the light on your power supply.

Green power supply light: If your console has three flashing red lights and a green power supply light, your console needs to be repaired. The warranty period for three flashing lights is three years from the original purchase date of the console. If your console is not covered by the three-year warranty period, you can still get your console repaired for a fee. Start the repair process online.

If your console has four flashing red lights, make sure an Xbox 360 A/V cable is connected to the A/V port on the back of the console.

Red, orange, or unlit power supply light: Try the next solution.

1. Turn off your console.
2. Disconnect the power supply from the console and unplug the power supply from the electrical outlet.
3. Take your console and power supply to another room.
4. Plug the power supply directly into an electrical outlet. Do not use a surge protector.
5. Reconnect the power supply to the console.
6. Make sure that all three power supply connections are firmly secured.
7. Turn on the console.

Note If the console now has four flashing red lights, attach an Xbox 360 A/V cable to the A/V port on the back of the console.

8. Check the light on the power supply:
