I got my head all back together and the neck, etc. I have a battery going through a 640 ohm resistor to a female extention plug. I plug this in to test the LEDs. Each one worked very good but one did not. I checked reverse polarity on the circuit and the LED worked. I did not want to take the head all apart again (hassel). So , I simply turned the plug around not realizing if i were hurting something or not. But, it did not seem that it would damage the EZB because I was simply swapping ground and signal. I can't see very well, I may have plugged a plug in shifting one pin over. that would connect ground to hot or signal to hot.
Anyway, boiling it down, All of my digital pins do not work anymore.
Any ideas? I am thinking voltage regulator blown, I hope it is not the cpu. I am going to run the test that D.J. has and try to figure it out. The lights blink red and blue and it connects up. So , the bluetooth is working.
Wish me luck.

Totally up to you, however we will not repair the board after someone else has altered it in any way. If you are confident in your abilities, that would be the cheaper way to go.
@mel I mean if you can send it in the the factory I would do that.
When I do a search for the %A LDO POS REG, it puls up the LM1084. Am I missing something? or are they the same chip. It seems like they have a different pinout. I need the part # to the VR2.
