Three flashing red lights around the Xbox 360 power button
(nicknamed the "Red Ring of Death"), in lieu of the one to four green lights indicating normal operation, represent an internal problem that requires service.Warning signs may include freeze-ups, graphical problems in the middle of gameplay, such as checkerboard or pinstripe patterns on the screen, and sound errors, and the console only responds to pressing the power button to turn it off.These events may happen once or several times until the hardware failure occurs, or not at all. If the console freezes occasionally, the error will not necessarily follow. When the error does occur, on the user's attempt to turn the console on the three red lights are seen and the console does not function.
