I have a first generation IPAD. I took it to the store to show pictures to a friend. Then I went to get some food. I left it in the car it was about 30 something degrees. I go home and turn it on. It is blurry, fuzzy, lines etc. It was really rock cold, and for like the last 11 hours I have been trying to make it warm no success. Does anyone know anything I can do. Or is this a lost cause? It charges, plays music, I can see half of a picture when I slide my finger to the left, it shuts off, slides on. Should I leave it on or off? Thanks!
