i got some time yesterday to test away, and got a tip from yuktsi, figures you need all the rgb leds connected for it to work properly, hence also adding leds on RGB 1 and 2 which are located above the arrow cluster on the top side of the pcb, so i had to attach wires to the bottomside holes of the rgb connections to test it, yesterday when i connected everything i got 4 leds to work, seems i have not attached nr5 properly or the led is broken or smth.
