Xbox 360 / Xbox 360 Elite
Error code symptom
Do you get an error code from your Xbox? If your Xbox experiences a hardware or software related problem, you may be faced with an error code displayed on your screen. The message will be multi-language and have an error code at the bottom. Common error codes are error E74 and error E73.
The E74 error occurs when the Xbox 360 console experiences a hardware failure. You can verify that you have the error by turning off and on your console to see if the code is still displayed, to confirm that your console needs to be repaired. Error E73 indicates a general hardware failure or problem with the ethernet port.
