is the Led strips WS8212b burned ?

Hello an somebody help me :disappointed_relieved: :disappointed_relieved:
I had led strip ws8212b 1 meter 60 led controlled by uno clone,
I had planning making vu meter with signal sound
I have finished this installation but not working perfect, I think the problem is coding or component
At that time Iā€™m soldering a board with uno without turning off the uno and components
And coding not stable,
Then I forgot to input dc 19 volt amphere 2.3 to my board which should be 5.5 volt
I have two problem now

  1. Uno led always on
  2. The led strips only 2 led on (for the led strips I try to fix uno finally I control with multimeter the result I cut 2 led because the DIN is not working , but stiil live only green lighting

I hope the leds still working with uno, I try again with capasitor 1000uf n resistor 470
The result in one time the leds on (no.11) but only one is blink higher white coulor
When I put again one time the leds only 2 (no.1 Green & 7 blue ) thanks before
