Pironman LED strip not working

Hi, I have installed new Pironman mini pc chasis and it seems due to some reason LED strip is not working. I tried to enable the RGB lights through command line, it did say it succeed but not light glowing. Please help to resolve this issue if I am doing something wrong here ? or do I need to get replacement for this if it is faulty part ? Thanks in advance.
