Sewing machine not turning on

So basically I was having trouble with the bobbin and when I tried to lock it in my machine the thread stops moving, I fixed it, cleaned my machine, and oiled it, and the light was flickering. I turned it off and tried replugging it in and now the whole machine won’t turn on. What do I do? It’s a brother LS2350 and I really don’t have the money to get it looked at
