General I/O Malfunction, could be caused by an error with any of the I/O devies such as A/V port, USB, Hard drive, DVD drive, etc.

GPU over heating -ensure your x-clamps are installed properly. If you are receiving this error after disassembling your console make sure to all 8 of the heatsinc screws are tightened securely to the board/heatsink holes. There is a problem with the Southbridge Chip usually dealing with how it connects to the mainboard (cold solder joint/bridged solder joints) Possibly Power problem could be the PSU could be the GPU/CPU, somehow the console isn't getting clean power from the power supply. Possibly a Network Interface problem (might be fixed by loosening the x-clamps)

If the screen is blank or you would like additional information follow the instructions for determining the secondary error code in the section below. The Specific Type of hardware failure can be determined by the error code displayed on the screen. For more information about ventilation, see the "More Information" section. Verify that the console has sufficient ventilation and that the fan is operating. Do not turn on the console when the console is hot. You may have to wait several hours for the console to cool enough. 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. If these steps do not resolve the behavior, turn the console off, remove the hard drive, and then turn on the console. * Unplug the power cord from the wall socket. * Unplug all the power and AV cables from the console. If restarting the console does not resolve the behavior, follow these steps:

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) This is also speculated to sometime be caused by a problem with the southbridge chipset on the motherboard.Ġ102 - unknown error - littereally means the console does not know what is wrong. Here is how you interpret the LEDs to get the code number:Ġ003 - power problem could be the PSU could be the GPU/CPU, somehow the console isn't getting clean power from the power supply.Ġ020 - not yet known, possibly overheatingĠ021 - DVD Drive Time out - Can be caused by problems with a firmware flash. 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. The LEDs will go back to the 3 red flashing lights. The LEDs will now blink the forth number of the code. The LEDs will now blink the third number of the code. 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 first number in the code (as described below). Press and hold the sync up button (the small white one), while holding that button press the eject button. Turn the xbox 360 on, and wait till the 3 red lights are flashing. The specific type of hardware failure can be determined by a "hidden" error code: 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. Wipe the metal area thoroughly, and then try the AV Pack again. The metal area is the end that plugs into the console. If the four flashing red lights continue to flash, try wiping the metal area of the AV pack with a dry cloth. Disconnect the AV cable from the Xbox 360 console, and then reconnect the AV cable to the Xbox 360 console. Make sure that the AV cable is correctly connected to the Xbox 360 console. The AV cable cannot be detected by the console If you have encountered one of these service errors: These numbered error codes are shown below with their corresponding LED Code and may helped you with your trouble shooting. There are many different patterns which will also show a numbered error code. These lights/codes are used to determine the problem with the console. Whenever the Xbox 360 Console has a problem it will display error lights/codes.
