Why wont my speaker turn on even though it has a green light?

hi ! so to b more specific & helpful, i have the doss e-go II speaker. i got it september of last year & it was working perfectly fine until about 2 months ago. whenever i charge it, it automatically has a green light, no matter how long ive been charging it. ill charge it for hours & itll have a green light on, but it will never turn on. it wasnt old when the problem started & still isnt. it hasnt even been a year since i got it & it already doesnt work. if i can fix it please let me know. thank u !
