If it has to be the error code E73, you got the most irritating problem of all.
So many people, have the worst time of all trying to fix this error, E73 happens to be the worst!
Let’s first take a look at why it might have happened, and what causes it to happen.

Some say it’s something to do with power surges, for example:

Say there was a thunder storm and you’re playing your favorite game completely ignoring the fact that lightning was striking everywhere but on you and all the sudden your power goes out and comes back on just as fast as it went out, creating a power surge zipping right through the power cord of your Xbox 360 and frying the Ethernet port or motherboard.

That’s just one scenario!

The other, could be the Ethernet port just got twisted or burned out somehow, so the best thing you can do, is to take it to a professional but only after you’ve checked the necessary components first.

Like I said, the Xbox 360 error E73 is the worst one of all, because it’s really difficult to pinpoint the exact problem even after disassembling your console.

Make sure to check the AV cables, Power Supply cable, and any other extra attachments or accessories you may have, in fact remove all extra attachments or accessories, then try to power on your Xbox, if you still have no luck, it’s definitely something wrong with hardware failure.
If in fact it is hardware failure the best thing you can do, is to send it back to Microsoft if you’re covered under the warranty, remember not to take apart your Xbox 360 if your still covered under your warranty, if you’re not covered under the warranty however, the best thing you can do is to take it to a professional, where it could become quite pricey but much less than Microsoft will charge you.

You really don’t have too many choices when it comes to the Xbox 360 error E73, you can either fix the problem yourself by installing a newer Ethernet Port but that’s really taking a big chance so I don’t recommend it, sorry I could recommend anything other than having a professional fix it for you.

Thanks for reading,

    I had the E73 problem last night. I fixed it very quickly using a YouTube video demo. In a nutshell: Look at the rear of the X-Box and peer in through the vent holes to see the two cooling fans. Insert wooden 'sticks' (cocktail sticks are a little too thin, but will work at a pinch!) to stop the fan blades from spinning. Turn the X-box on. After 10 - 15 minutes the box will over-heat and the two red lights on the left of the ROD panel will light. As soon as this happens remove the AV plug and remove the mains plug. Then withdraw the two wooden sticks. Plug AV plug back in and also mains plug and re-start the X-box. The fans will begin turning at high speed to cool down the motherboard - but the problem should be fixed. It worked for me straight off. On one of the videos the box had to be turned on and off several times before the green lights came back on. It's worth a try before spending a lot of money!

    To fix the error E73 I had just this morning i got it after playing halo 3. I did research and founf out how to fix it. I took two thick paperclips and stuck it in thge fans on the back to stop them from spinning. Wait five minutes with the clips in the back and the first and the third lights will light up indicating the box overheated. oh yah before you do thihs unplug the av cord and keep the powercord in. But when it lights up unplug the power cord and plug wverything back in and it shouls work if it doesnt then you shouls call microsoft

    Thanks for the tip,, no matter how long I stuck at it I just could not get it to work, darn...

    I have also read that this is the worst type of red eye, as it is the hardest problem to solve or even identify. I read on line that Microsoft wont fix it free of charge, now thats bullshit. I will ring them on Monday.

    Thanks anyway, glad you are up and running and hopefully pawning all you meet on the battle field.
