Quoted from wizzardz:It looks like the top left connector in the first picture above isn't lined up correctly. Can't tell from the pics but looks like a few might be misaligned.
That's just the black cover that's misaligned I think. They slide pretty easy. The boards actually look very clean from what I can see. Nice pickup. I love me some Black Knight! Keep working on it. You'll figure it out. I just started working on pins about 8 months ago and I can pretty much do any repairs including board repairs. You sound excited which is important. Keep learning. Keep reading. Keep asking questions here on Pinside, and you'll have a great BK before you know it.
