How to tell what error code your Xbox360 has (credits to uncle Az):

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

2 RLOD Error codes

E-Code / Secondary Error code: E05 (No Audio/Video) / 0011
Binary/Hex: 00000101 / 0x05 -> 5

Known fixes:

1) Make sure the CPU heatsink is making good contact with the chip, apply a thin layer of compound and put the heatsink on without screws, make sure it gives a good imprint then.
2)Replacing the CPU X-Clamps/Applying new thermal compound
3) Cut the temperature sensor trace

Description:

This error appears when the CPU overheated, after that the xbox locks itself until it cooled the chip down.The reason for that is that the heat cant be dissipated to the heatsink/ the heatsink isnt cooled properly...
This can be the result of improper thermal compound usage or if the error comes up instantly while booting the console, the heatsink will likely not be making any contact at all with the chip.
In rare cases it can also be a faulty temp sensor.

E-Code / Secondary Error code: E10 (No Audio/Video) / 0022
Binary/Hex: 00001010 / 0x0A -> 10

Known fixes:

1)If you soldered anything to the mainboard before it occured, whatever you are powering from this point is drawing too much power so get rid of it.Also get rid of everything that you can see that might bridge anything near the GPU.
2) X-Clamp replacement
3) Reflow GPU and HANA chip
4) If it\'s not the GPU/(H)ANA, it might in rare cases be the CPU and can be fixed by reflowing the CPU.
5) if you flash with xell on JTAG-fixed xbox360 this will appear, flash back to original.
6) also can be caused by a broken trace (see link below).

Description:

This error is caused by a bridged/shorting solder joint under the GPU, (H)ANA-chip or in between.It can also be power related though, for example if you are drawing power from one of the regulators that power the GPU and HANA-chip.Can also be a component that is missing or damaged so look for missing parts near the GPU and the HANA chip. In extremely rare cases it might also be related to the lines that lead from HANA to the CPU.
The chances are however higher that it is the GPU than the HANA chip so you should always first concentrate on the GPU.

Another cause could be due to a broken trace under the board near one of the ram blocks, check the picture in the reference section. Thank you arvydas for reporting this solution!
