All of a sudden it just died on me. I've tried several different batteries and it won't turn on. It'll light up the logo when I first put it in but that's it. There have been a couple of times it'll turn on&I can get 3-4 hits then the display will freeze up and I have to remove the battery. Once I replace it I can't get the mod to turn back on. It's still under warranty but I wanted to see if there is a quick fix first so I won't have to go without it
