E75 Error

[ilscuro]

I've just tried to repair a 360 console which had 3 red lights, followed my usual method which has worked in the past, but now i'm getting 1 red light and an E75 error, there are conflicting posts on the net as to what this could be, and as there are a number of experts here on DF i was hoping for some help please.

E74 or E75?

They're both related to the video card I think

E75: Ethernet Error - Couldn't read ethernet phy vendor: Strange but sometimes caused by the DVD drive not being connected properly.
Check the solder joints under the lan socket and the drive fw
