Sorry for the long delay. Been busy.

I went ahead and touched up the solder points for all the pins. But I still got sporadic results. Since I was going on a road trip, I babied it along. Got it to boot up. Put the empeg back together piece at a time making sure it booted up after each step, and hoping and praying that it still booted up when I was done. It did. Got it in the vehicle, and still booted up. So I at least had music for my road trip. My confidence that it's now solid isn't quite there. I haven't removed it from my vehicle for fear of it not coming up again.

I couldn't find any corresponding solder points on the underside of the motherboard, or am I missing something there?

And I've checked from pin end to solder connectivity, and that's fine, but it's obviously a bit more difficult to check from pin to final destination, so any other suggestions?

Thanks for the help guys..
