Here are all of the errors on the Xbox 360.

Red Ring of Death

Error: When the Xbox turns on, either Q4 (1 ring), Q1 and Q3 (2 rings), Q1, Q3 and Q4 (three rings) or all quadrants (4 rings) flashes red.

Trivia: When you get the 3-quadrant error, if you hold the console sync button and tap the disc eject button, the lights will change. You can extrapolate a number based on how many lights are flashing each time you press eject (up to four digits, before it goes back to the ring error).

Variants: 

• On the Xbox 360 S and E models, the power button utilizes a different design that does not incorporate the same style of lighting that past models used. Due to this, errors are indicated by a flashing or lit red light in the middle of the power button, dubbed the "Red Dot of Death" by some, depending on the error.

• There was also another form of the RRoD where if the power cable was loose, the Xbox power button will display a flashing center light.

Technique: The quadrants blinking.

Avaliability: Seen if a hardware component fails (1 ring), when the console overheats (2 rings), more hardware components fail (3 rings), the AV cable isn't connected or due to a serious error (4 rings), or sometimes when the console is modified (S and E models).
