But unless you have to correct soldering iron and skill set, you can ruin the board removing and replacing the parts, if indeed thats what went out. The thing is, you typically do not see those just going bad on you, something could be shorted and making them shut down. When you do power up the board, another way to find bad parts is by thermally checking them. Carefully use your finger (unless you happen to thermal gun) and look for parts that are screaming I'm hot and burning up. Warm is OK. Hot that you say oh $%&^ when you touch them isn't. That would be my next step.
    I will take a look for "$%&^ hot" components, either when I get out of work today or in the morning.

    I will also measure the voltages on my other F16v3 (a higher Rev board) to see if I can identify major differences.

    Measured the voltage on the working F16v3 and I have proper reading on all 3 Voltage regulators.

    There will also be 1.8V and the FPGA core voltage of around 1.0V. Since the ethernet lights aren't working, I might suspect 1.8V may be out. Just be careful measuring, go across the caps because its easy to slip using the meter probes and once the smoke is out of the magic chips, thats it.

    Bumping this, since I just had a second Falcon fail in the EXACT same way.

    Since this is the second failure, is it possible you are power injecting into the first pixel using a different power supply, and not disconnecting the VDD lead from the controller? If I was in your shoes, the first thing I would be thinking is, what am I doing wrong? So that I don't get a third?

    No is is not possible. I was not power injecting anything. The board was powered by a single MeanWell 5VDC 60A Power Supply.

    Could you post photos of each side of this controller ?

    Is there a sequence of button press to do a POST on these controllers ,or can you access factory reset at initial power up ?

    Just a thought .
