For anyone following this thread, PJ Allen has been graciously helping me via Private Messages and we are testing the board still with good progress being made. I will post some files when we get something more permanent. 

On a side note, I had a couple of P channel FETs blow out on the display board. I'm wondering if the manufacturer uses the same FET for both Red and Green LEDs. The manual/datasheet never states using both on at the same time to get a yellowish/orange LED effect. I tried to turn both LEDs on at the same time during some trial coding and saw the smoke and smelled the burn. A bit surprising but I beleive I can repair it when the parts arrive. In the mean time, I just have to acknowledge that both upper and lower Rows 12, 2 and 4 are out on the LED display temporarily.
