NZXT S340 Razer Ed. Led Problem

Hi everyone, i've bought a NZXT S340 Razer Ed case as 28 oct 2018. Everything worked properly until like 2 months ago when the beautiful green leds started to dim. After a month or so, the leds switched off completely. I've tried to plug and unplug the wirings and switch on and off the back button without success. Bought from Amazon, asked for RMA but the product is out of production, so only option is refund with case send back to amazon. No online store to my knowledge has S340 Razer ed in stock (i live in Italy). There is some option to replace the Leds DIY?
