Lexibook tablet junior power touch

Hey guys, i got a problem with my lexibook and i have no idea what's wrong with it. i have sent it to multiple computer shops in order to fix it but even they couldn't find a way to fix it. So i'm hoping you guys have any idea whats wrong with it.

So far from what i did myself, i can access it's recovery system and do a factory reset on it but it still doesn't work. i haven't found anything useful on the lexibook's website regarding this problem. Any help from you guys will be appreciated
