What to do if the WS2812B LED strip does not work after a short circuit?
I bought an address tape to install in a computer where there is a corresponding connector. I installed everything and for some time it worked, but then I closed two wires for additional power (I did not pay attention to them), the computer turned off and one LED worked on the tape.
Most likely you burned the controller. But here I could not find the motherboards or cases with a controller for it, did you accidentally connect to the connector for connecting the RGB tape? In any case, now look at the circuit and look for damage in the circuit with the controller of this tape.
