I got this from llama.com this is not mine and i take no credit i just thought this would be quicker for those who need this and dont know where to go
--==ERROR Codes==--
If there is a problem with the Xbox360 The LEDs in the ring of light will flash in a particular pattern. The pattern itself leads some insight to the problem. Certain patterns will lead to numbered error codes which will provide further insight to the problem. The numbered error codes are described below their corrosponding LED code.
these are the codes we know so far...
Please contribute if you know of new codes that are not part of this list.
=============================
Sections 1, 2, 3, and 4 are flashing red
- The AV cable cannot be detected
/ \
\ /
THINGS TO TRY
1. Make sure that the AV cable is correctly connected to the Xbox 360 console.
2. Disconnect the AV cable from the Xbox 360 console, and then reconnect the AV cable to the Xbox 360 console.
3. If the four flashing red lights continue to flash, try wiping the metal area of the AV pack with a dry cloth. The metal area is the end that plugs into the console. Wipe the metal area thoroughly, and then try the AV Pack again.
4. If the AV cable is correctly connected but the four red lights are still flashing, substitute a different AV cable if you have one available.

- General Hardware Failure

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
0001 power supply problem
0002 power supply problem
...
0010 over heating
0011 over heating
0012 over heating
0013 over heating

0020 (Not yet known, possibly overheating)
...
0022 GPU Error / GPU Overheating
...
0102 unknown error - littereally means the console does not know what is wrong. possibly a short or cold solder joint somewhere (2 reports of people repairing this, one was removing moisture build up inside the console, the other used a hot-air rework to reflow the BGA Ram chips)
...
0110 (Not yet known)
...
1022 (Not yet known)
THINGS TO TRY
1. Try restarting the console.
2. If restarting the console does not resolve the behavior, follow these steps:
* Turn the console off.
* Unplug all the power and AV cables from the console.
* Unplug the power cord from the wall socket.
* Firmly reconnect all the cables.
* Turn on the console.
3. If these steps do not resolve the behavior, turn the console off, remove the hard drive, and then turn on the console. If the 3x Red LED error light is no longer displayed, turn the console off, re-attach the hard drive, and then turn on the console.
=============================
Sections 1, and 3 are flashing red
- Overheating
/ \
\ /
THINGS TO TRY
1. Let the Xbox 360 console cool.
Note You may have to wait several hours for the console to cool enough. Do not turn on the console when the console is hot.
2. Verify that the console has sufficient ventilation and that the fan is operating. For more information about ventilation, see the "More Information" section.
PREVENTION SUGGESTIONS
To try to prevent this problem, use the following precautions:
* Do not block any ventilation openings on the Xbox 360 console.
* Do not put the Xbox 360 console on a bed, on a sofa, or on any other soft surface that may block ventilation openings.
* Do not put the Xbox 360 console in a confined space, such as a bookcase, a rack, or a stereo cabinet, unless the space is well-ventilated.
* Do not put the Xbox 360 console near any heat source, such as a radiator, a heat register, a stove, or an amplifier.
DO NOT EVER PUT YOUR CONSOLE IN THE FREEZER OR OUT IN COLD WEATHER
Some people think that doing this might help "fix" an overheating console, in fact doing so could cause even bigger problems. Electronic devices like your console are made to function at and around room temperature, extreme cold temperatures can often cause just as many problems as extreme warm temperatures (such as overheating). Also if the console is located in a dramatically cold area while running, the difference in temperature between the hot console and cold air can create condensation which in turn will short out your console making the situation far worse. Condensation will happen more quickly if your console is overheating due to the greater difference in temperature. In short... DON'T DO IT.
