my friend's xbox just got e74 out of the blue. if there were any warning signs he was not much aware of it. he did some makeshift troubleshooting before sending it to microsoft:

1. Turn off the console, disconnect all the cables, and then reconnect all the cables. Turn the console back on.
2. Turn off the console, and then disconnect any accessories that are connected. For example disconnect any Xbox 360 controllers, Xbox 360 Memory Units, and the Xbox 360 Hard Drive. With the accessories disconnected, restart the console to see whether the problem continues to occur.

This can help determine whether the console or an accessory is experiencing the problem. - it is not the AV cables or even the port where we connect it, it is one of the hardware failure and if not able to solved this by following the troubleshooting steps provided then we just hoped that your console will have the extended warranty to send this console for repair.
