I have plenty of power (5V 60Amps) but out of 6 strips (5Meter 150LEDs each), three of them do not light up all the way to the end...the very last 3 to 5 LEDs do not function. When I connect another strip to these strips, they also fail to function, even when I add another 5V30Amps to the connections. Controller has 3 channels and each is set to control 300 lamps. Should I just cut away the parts that do not function? Or is this an indication of another problem?

  • So the same strip fails on the same spot? It might be cold joint on prevous chip output or on input of dead one. Or dead one is actually dead. Or previous has dead output. If you have spare strip, you can cut out one (or more) dead pieces and solder the rest (or some spare pieces of another strip) – KIIV Apr 19 '20 at 15:54
  • Most likely the voltage has just dropped too much over the ultra-thin cheap chinese copper traces for the LEDs to light any more. – Majenko Apr 19 '20 at 15:57
  • does your program tell them to light? – jsotola Apr 20 '20 at 3:21
