Red flashing light and having a code E73 - Microsoft Xbox 360 Pro System Console

Red light problem can be fixed! there is a XBOX 360 repair guide available that covers this problem and also all other common XBOX problems. You can get your copy XBOX 360 Repair Guide, you can download it and get help to fix your console. Please feel free to message me if you need further assistance...click here

When turning on the Xbox 360, a red light would be flashing at the fouth section of the Ring of Light. You should then recieve a ghost screen indicating an error E 73.
You recieve a screen error E 73 and section 4 of the RoL flashing red. This type of error was caused by a General Hardware Error relating to the Ethernet Port not functioning correctly or became faulty and unable to operate even with or without an Ethernet Cable connected to this port. The secondary code would be identified as 1021 for faulty ethernet port. I believe that there is no fix at the moment. If you encounter this error, I would suggest call 1-800-4MY-XBOX or visit www.xbox.com/support
The specific type of hardware error can be determined by these hidden codes:
0001, 0002, 0003, 0010, 0011, 0012, 0013, 0020, 0021,0022, 0023, 0030, 0031, 0032, 0033, 0100, 0101, 0102, 0103, 0110, 0200, 0203, 1000,1001, 1002, 1003, 1010, 1011, 1012, 1013, 1020, 1021, 1022, 1023, 1030, 1031,1032, 1033, 1100, 1444 and up

• Note: There is known to be a temporary fix for this problem but is not recommended if the device still has available warranty on it. Doing so will avoid it's warranty, thus for you will pay $100 if sent for repair.

The Sticks Method:

• Requirements: Xbox 360 (Power Cable and Composite/Component/HDMI Cable), two sticks (Like toothpicks, swabs)

1.) Turn off your Xbox 360 and unplug everthing.
2.) Get two sticks (Something like toothpicks or something that could fit in the back of the Xbox 360.
3.) Insert each stick to jam the two fans at the back of the Xbox 360 to prevent it from spinning.
4.) Plug back cables (Power and Cable connecting to TV; the RRoD will not appear unless the cable to the TV is connected).
5.) When RRoD appears (One Red Light), wait for about 10 to 15 minutes or maybe less for the Xbox 360 to overheat.
6.) At this point, you should get two red lights (Resembles Overheating Error) so remove the two sticks so that the fans will spin in an increased speed. After a few seconds, the Xbox 360 will turn off to cool down (RRoD will still appear).
7.) Unplug only the cable connected to the TV. You can unplug the power cord if you want to. Then let it cool for about 30 minutes or so (Feel the Xbox 360 if it's cool or still warm)
8.) Replug all wires and turn your Xbox 360 on.
The Xbox 360 should now be able to boot to your Xbox Dashboard. I don't know how this fix works but it's only temporary. Note that doing this continually would cause it to now work even if you try to redo this fix again and again. Doing so would make other hardware components to fail permanently such as the GPU for example.

If this first temporary fix did not work, do the second method: The Towel Trick. You can find the tutorials in Youtube. Again, this is not recommended if you have warranty left and never do this continually. Your Xbox 360 would completely and permanently fail after that. if it doesnt help after all this....I suggest sending it to Microsoft for repairs
