Case led problem (not starting)

[The Best Tintin]

My case leds won't start, i have leds in my fans and 2 strips which came pre-installed the fans each had one 3 pin for the fan and a 2pin for the led and the strips also had 2 pins all of the 2 pin leds were connected to the led button with 2pin connectors coming out of the board and a single molex connector was also connected to the PSU But when i clicked the button for the leds none of them worked and the board which had the button also looked normal.

My case is a Primera Pm01 from sliverstone

First time using this, any tips to be more precise are welcomr

Have you tried reversing the connection, most often a positive and negative terminal mistake can render an LED non responsive. Don't worry it's not dead(at least I think so).
