Question about Microsoft Xbox 360 Console
E73 is an I/O Hardware Error. Usually due to a problem with the Ethernet port or supporting control devices. It's probably best if you send it to microsoft, especially if you have warranty.
Here are a few tips that might work to fix it:
1. Restart your console.
2. Unplug all AV cables, and also unplug the power cord from the wall socket. Once that's done, plug them all back in correctly, and put your console back on.
3. Take out the hard drive, and put your console on. If the troubleshooting error has been gone, put your console off, and get the hard drive in again. Than put your console back on.
If these tips didn't fix your Xbox 360 E73 error, you will have to open up your console, and fix the problem from within. You can do this by 2 ways. You either send it over to Microsoft, or you will actually repair the troubleshooter by yourself with a repair guide.
