    As an update:

    I received the MOSFET and voltage regulators I order from Mouser. I assembled a board with those two parts and all of the other 'September' parts. The board seems to work properly now. As someone mentioned above about there potentially being a voltage issue with the data signal, I wonder if the voltage regulator is necessary even when 5V pixels are being used...

    I think I might try the old MOSFET on one or two of the new boards to test my theory of needing the voltage regulator even with 5V pixels. I just wanted to let everyone know of my progress thus far.

    I assembled a board with the old MOSFET and the added 5V voltage regulator in IC1. Everything works properly with no flickering.

    It would appear that the voltage regulator is necessary even though I am running 5V pixels. It's possible that it's an issue with these particular pixels (not from Ray Wu (see above)). In any event, I will continue to assemble the two dozen or so boards I'm gonna use for my display and post an update if I have any issues related to the flickering I was experiencing before.

    Thank you for keeping us in the loop as to your progress and findings .I may have to dig out the pixel pops once again after all !
