when I say they burn, they usually get short and that's why when you try a led tester per strip, only the 3 on the left (on the back) turn on each strip
Hello: Thank you for answering the two is the solution, although I had tried led by LED and with the tester, I was struck that the two had the 3. led in poor condition and did not want to take them off, but finally I had to do it. and as I placed them in the three fichitas that I have two black and red and blue and red, they lit me differently. And it confused me. Thank you
In the previous comment where I say they usually get short I was wrong, it is usually open and that's why when trying on strips they only turn on 3 of each strip.
