You are correct! Unfortunately, I believe it was @sqw who said that the board is not an easy fix for Pro users. The passthrough slot on the back has rivets that make access to the board not as easy as it is on the basic models. I did do an in-depth repair guide, but again, that was on my Basic.
Sorry to hear about all of this. The first time my machine was down, I felt sick. I hope something is able to work out in your favor.
