The Xbox 360 Video Game Console has a “Ring Of Light”, a circuit of 4 bi-color LEDs, with a green LED in the centre. This is used to indicate what state the console is in, and allows the user to diagnose faults with the console. Each of the LED “quadrants” has a number:1 is upper left,2 is upper right,3 is lower left and 4 is lower right. The Position of the numbered quadrants stays the same whether the console is placed horizontally or vertically.

Powered On

The power LED is illuminated green when the console is switched on and operating normally. The number of quadrants lit indicates how many controllers are connected.

Hardware Failure

When a failure of a hardware component occurs,Q4 will flash red. Usually, a two digit error code is displayed on the connected display(such as E74)

Overheating

When the temperature of the console reaches an unusually high level, the console will shut of the CPU and GPU, run the fans at full speed and flash Q1 and Q3 on the ring of light, until the console has cooled sufficiently.

General Hardware Failure

When a failure of one more hardware components occurs,Q1,Q3 and Q4 will flash red. This is similar to the one red light error, but there is no error code displayed on the connected display.

AV Cable Error

When the AV cable is not detected, due to it not being plugged in or due to a more serious problem, all four quadrants of the ring of light will flash red. This error code is not displayed on consoles with HDMI connection.
