Screen shows only "Kindle Fire"
I cannot get my Kindle Fire to boot. When it is powered on, the screen shows the Kindle Fire logo, and that is it. I noticed that someone else had the same question, but the only answers were for a hard reset. I have tried that numerous times. I've also tried charging it fully and letting it discharge completely before recharging again, all with the same result. I called Amazon and they said, "Sorry, out of warranty, we can give you a discount on a new one." Is this fixable?
