Go back and take a another look at the soldering. See here for a general reference:

These two pins looks good, so you can also use those a reference:

But check all the other pins. Maybe a solder bridge short here:

And any pins that look like this may not be wetted out enough on the pads:

Pins relocated and resoldered according to the tutorial provided.
All pins tested with multimeter, no short circuit, connectivity of the pads and pins are fine.
Run animation demo code, abnormal result.

Thanks. That does look better. There is still a chance that something like a solder bridge may have done some permanent damage to the HAT by shorting pins. But let's just replace it and see if that helps. The second HAT works, so we at least know the rest of the hardware should be OK.

Send an email to support@adafruit.com with a link to this thread and your order number and they can send you a replacement RGB Matrix HAT (PID 2345).
