Dead leds on knobs

  • Since last year the leds started dying on my kemper, first it was one on the gain knob, know there are three (two on the gain, one in the volume). I can still use it without any problems, but i do wonder, is there a way to replace them without sending the unit to the manufacturer? my warranty is long dead (bought 2nd hand) and i'm on south america so i guess i can only fix it by myself, lol.
