Panic 99 pixels not lit

[ItsMeBobO]

Five minutes staring at the pixel tree with an entire string not lit right in the middle.   Pixel 1 stays lit.    How can I get a spare string delivered fast?  How can I mount it in place since entire tree is up?   Should I splice in a new pixel 1 is racing through my head.

First  reboot ... same    Check all the wires  ... same.      Idea!   Spray some corrosionX in the connection.    Thank god that worked!     All 100 lit and all 3200 in pixel tree are dancing.   Phew.

Rhetorical question wasn't clear

Yes, sounds like a failed pixel.  Is the failed one at the top or bottom of the tree?  Assuming you have spare pixels, I would splice in a spare.

I always have this quandary : Is it a bad output of Node1 or a bad Node2 input. But I see it was a poor connection.

The other check, its to always swap ports to see if the issue follows the string or stays with the port
