Here is what the board is doing:

Different patterns each time you turn it on but garbage every time. The start buttons are on solid and not blinking. It's definitely a board issue as I have another board that works fine in this cab.

Any suggestions?
 
Force the reset line high (short to +5V) for a moment and look what happens.

If it runs, you may have a problem in the watchdog circuitry (like I did).
