To be honest, I am not 100% sure. I did pull the connectors and clean off the contacts, then reseat everything. I really didn't see any change until I metered the voltage at the ARII +5v pins and then all of the sudden it came to life. I will probably pull the ARII board in question and reflow the solder on the connector pins, as I am wondering if there is an issue there, and if not, possibly the power brick supplying the volatge to the ARII's. I initially ony metered 1.8v on the display PCB at the +5v test point, and then went to the ARII. I have since powered it on several times and it seems to have settled in. I am going to leave it off for a bit and try it again to see if it shows the same issues or not.
