Hi, I bought my teen son a brand new ipad mini for christmas this past year. He accidentally threw out the box so I don't know the model number offhand. He cracked the screen quite badly and now won't turn on. I took it to a local repair company since apple care won't cover it, and they told me that this particular models screens can't be repaired due to possibly damaging the motherboard. Does anyone have any experience with this? I haven't been able to find any information online about this issue.
