Open Tray (Dead DVD Drive)
E74 (Exx)
E(XX) Errors are point specific errors. This causes the system to cease operation and display one blinking red light in the lower right quadrant. They range from hard drive failure, to bad DVD drive configurations and other components inside your XBOX. By far the most troublesome is the E74 Error.
An E74 error is when the lower-right quadrant of the ring piece indicator flashes red and displays an error message in multiple languages: "E74 System Error. Contact Xbox Customer Support". The error is caused when there's a video problem, because the Xbox 360's hardware scaler chip is damaged.
