Charging but no charging indicator’s

I have this Jbl Xtreme 2 that had no other issues other than when plugged in with the charger no light indicators at the bottom turn on/light up as well as the power button at the top doesn’t turn on or flash but would still charge regardless and recently I’ve tried resetting it to try and fix it, but accidentally held the wrong buttons and put it into stationary mode and because of this problem when plugged in it thinks that it’s not being powered or charged and I can’t get it out of stationary mode because of it. Could this be something to do with the power connecter inside or a motherboard issue?
