Mine has done the same thing! This is very disappointing. You have a year manufacturers warranty on your FitBit, but beware. My first FitBit died after a year and they send me a replacement, the problem is the replacement they sent me is a complete dud. I contacted them to let them know my replacement had the black screen of death just like my first one and they told me they would not send me another replacement because my original FitBit was now out of warranty. I have had my replacement for about a month and I knew there was something wrong with it as soon as I synced it. It was having trouble syncing and counting steps. I thought maybe if I did a factory reset on it it would work again, but it completely died because I had the chance. Now I am out of the $200 I spent and they told me I had to buy a new product. 😞
