Rocky & Bullwinkle: power issue discovered???

I got more gobbledygook on the DMD, meaning CPU board not powered, so I took some time to do a meticulous analysis of what WIGGLING might right things.
In the end, I don't think it's the capacitors.

While running through my tests, I noticed some tiny sparks coming out of this 3x4 connector:

center right.  yeah you.

So in that connector, the upper right wire was having tiny sparks.  I uplugged it, squished the wire in a tad more, and yay the game plays.
So this might mean the board isn't in dire need of resoldering, just that connector needs work!  So will my adjustments be enough?  We'll see.
