Xbox bottom right ring is blinking red

This is taken off of teamxbox.com

It is an explanation of the bottom right light blinking red, how to tell exactly what it is, and so on. If there is general hardware failure on your xbox, microsoft posted on their site that you send it in for free repair and also get 3 year extension to your warranty.

Use this guide to determine exactly what is wrong, what hardware is failing, and hopefully we can figure something out. Please get back with me when you can, I would really like to get you up and running again, cause I know how it was when I couldnt play my xbox, I hated it. Good luck!

=============================

--==SECONDARY ERROR CODES==-
The specific type of hardware failure can be determined by a "hidden" error code

• Turn the xbox 360 on, and wait till the 3 red lights are flashing.
• Press and hold the sync up button (the small white one), while holding that button press the eject button.
• The LEDs will now blink the first number in the code (as described below).
• Release the eject button and press it again.
• The LEDs will now blink the second number of the code.
• Release the eject button and press it again.
• The LEDs will now blink the third number of the code.
• Release the eject button and press it again.
• The LEDs will now blink the forth number of the code.
• Release the eject button and press it again.
• The LEDs will go back to the 3 red flashing lights.

You should be able to determine the difference between the 3 flashing lights and the error code lights by the rate in which they flash.

Here is how you interpret the LEDs to get the code number:

• All four lights flashing - 0
• One light flashing - 1
• Two Lights flashing - 2
• Three lights flashing - 3
