this is the second cube i have made in 2 days.
you would think being $120 from jaycar it would come with clean components.
As both kits had black tarnished leds.

the second is great but i noticed the bottom layer wont do red?
if someone could please help
also the start up sequnce the first 2 leds at the front right all the way up light up

Check all of your solder joints carefully. I had a similar problem with one of the ones I built. I had missed a joint on one of the risers.
I also had another place where I had solder bridge a gap that it was not supposed to. I do not remember which caused the symptoms you are seeing, but once I found it it solved the problem.
I hope that helps.
