I got an error in my console e73erro
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
Sometiems you can fix this with a reflow, but its hit & miss (50/50) with this error, as the actual port may be faulty, but reflowing wont hurt to try, or you can sell it for spare parts on ebay and get another base unit.
If you wanna try to reflow, there is a
great 6part video guide on YouTube to view for free. 6 videos from the same
fellow, each video is a few mins long, and goes over everything for you.
http://www.youtube.com/user/ohiocitysales#p/u and its free unlike some eBook site.
I actually
used the same method to fix over 450 Xbox360 units with no problems at all,
barring a few (but i have done nearly 500 so you expect a few problems along
the way), you just need a few things though like a heat gun and some thermal
paste. sounds hard, but it's very easy once you start!
Hope this
helps in some way.
