How to Troubleshoot an Xbox 360 With a Flashing Red Light

If all four lights on your Xbox 360 gaming console flash, you need to send the device away for factory repairs, but an Xbox with one flashing red light often is not as drastic and may simply require you to do a system reset. If an error code other than E74 appears, or if no picture appears on your television screen, you may be able to fix the problem. The only way to fix the E74 code is to send the device to Microsoft.

Instructions

- 1
  Press the "Power" button to turn off your Xbox.
- 2
  Remove the power cord from the back of your console, and unplug the cord from the wall outlet and from the power supply unit.
- 3
  Reinsert the cords into all three connections that you disconnected. There is no particular order in which you need to plug in these devices; however, it is important to make sure all connections are securely inserted.
- 4
  Press the "Power" button to turn the Xbox back on. There now will be a single green light at the top-left corner of the power button.
