Hi this is what that error code refers to:
E73: I/O Hardware Error - Couldn't calibrate HSIO Bus from edram: this error is likely caused by a problem with the Ethernet port or supporting control devices

this could mean a chip on the board has over heated and failed and this will need soldering to get fixed.

how ever try the following first
1 switch the xbox off and leave it off for at least an hour
2 remove all leads from the xbox and the back of telly also remove hard drive and anything else plugged into it
3 check the air vents on the xbox and make sure their is no dust build up, clean if needed with vac
4 make sure the xbox is not being used on top of carpet or dvd or sky box
5 make sure xbox is not in confined space it needs to have air circulating around it.

now plug all the leads back in and switch it on without a game in and see if you get the same error code or not try switching it on without any internet connection and see if you still get the code.

if after doing the above it still plays up then this will need work doing to it as the chances are its over heated

check if you have any warranty left and if you do take it back adn get it exchanged.

if your warranty is out then your going to need to get someone to look at it for you.

i charge about 25pound to fix these plus parts so it comes to about 30quid so you need to look around and see if you can find someone who will fix this for you.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

Hello my problem is in xbox 360 elite e 73 one light red

If you get the Xbox 360 1 red light message, it means that the problem is either with the DVD drive, or with the hard drive.

Fortunately, the Xbox 360 1 red light message is not something that you should worry about. In order to identify which of the two drives the Xbox 360 1 red light messages is referring to, just look the code number that the screen displays. DVD drive errors are identified with the codes E64, E65 and E66, whereas hard drive errors are identified with codes E67, E69 and E79.

Once you identify which error the Xbox 360 1 red light message is pointing to, fixing it is really easy. The guide available at will tell you what to do in each case, as well as what to do in case you get any of the other Xbox 360 lights messages. Check it out.

My XBOX360 says E 74, and has a red blinking light in the lower right corner.

Your console's GPU and/or CPU have overheated and are no longer functioning. You will have to send it to microsoft, (if you still have a warranty and want to wait 4-7 weeks) or you can e-mail me, I own DRAGONF1R3 REPAIRS and can fix your problem cheaply and in a third of the time.

One flashing red light on xbox360 ( not red ring)

The specific type of hardware failure can be determined by a "hidden" error code
Turn the xbox 360 on, and wait till the 3 red lights are flashing.
Press and hold the sync up button (the small white one), while holding that button press the eject button.
The LEDs will now blink the first number in the code (as described below).
Release the eject button and press it again.
The LEDs will now blink the second number of the code.
Release the eject button and press it again.
The LEDs will now blink the third number of the code.
Release the eject button and press it again.
The LEDs will now blink the forth number of the code.
Release the eject button and press it again.
The LEDs will go back to the 3 red flashing lights.
You should be able to determine the difference between the 3 flashing lights and the error code lights by the rate in which they flash.
Here is how you interpret the LEDs to get the code number:
All four lights flashing - 0
One light flashing - 1
Two Lights flashing - 2
Three lights flashing - 3

Once you get this code, go to:
To get the reason for the code.

I have 1 red light flash on xbox 360

Hi, 1 red blinking light is an indication of an electronic failure. The E 73 is the failure code. If this unit is under warranty, call Microsoft and they will issue a return label for the repair. Good Luck to you!

Bar light turns from green to yellow to blinking red

this is similar to the red blinking lights on the seems your cell processor has overheated resulting in a cold solder joint or worse bridged solder involving the BGA array...I have had some sucess in fixing these albeit limited. sony charges 150 plus state tax and sends you a refurbished unit.
