DiYLedExpress

This is one of the main reasons I will never do business with diyledexpress again. Half my connectors are like this. Copper is black, can't solder them at all. Was hoping to run my mega matrix tonight, not now. Had to jump on Amazon and order new ones. Diyledexpress will not even acknowledge the problem.

That's awful. I've seen marine wire like that, but new pigtails. Ugh

They had to have been manufactured like that, it is all the way up, many of them will not even transfer power or data.

You defiantly shouldn't have to...but have you tried a little vinegar treatment?

These are from the same batch....

That black wire is many years old, was probably stored in a wet environment and has completely oxidized. Almost impossible to solder.

My guess is DIYledexpress ordered from a crappy manufacturer.

Sandpaper will cut the oxidation off the surface, I have had to do that 2 or 3 times on my pixels when solder would'nt stick. Not sure if you do manage to solder them how the current capacity will be affected. I feel for all the people who were depending on their orders.
