Logic board didn't fix it. It's likely the LCD or the cable. Not gonna mess with it. The seller agreed to take the logic board back, so I will ship it back and get a refund.

I will sell the rest of it for what I can get to recoup the costs.

If anyone else wants to mess with it, let me know. I just want to recoup the cost I spent on it, plus shipping if it ships (I will ship cheapest)

It's very possible it could be the cable itself. These are known to fail. the LCD is the most expensive part, but that's also a possibility.
