Did you check to make sure the orientation of the ribbon cable was correct and not upside down?

Also make sure that your ground was reinstalled

Usually it is related to a bad 5v source when your dmd goes out so fast but since you stated that you changed out your mpu I assumed that the problem would lie there...if you know that the mpu that you installed is fully functional then I would check the power supply anything less than 5v no matter how small can be a problem, I believe you need 5.3v to be exact
