--==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
