I just got a good deal on this Samsung Galaxy Tab 3 10.1. The guy said I can have it for $100, but it won't turn on. If I can't fix it within 7 days, we can either return it and get the money back, or we can just keep it. I can still figure out how to fix it. I tried plugging it in, but the screen won't turn on or anything. The back of it DOES get hot, like it's charging. But the screen, lights, nothing will turn on. Does anyone know what could be the problem?
