Black lines appeared and increased then whole screen is black but still vibrates

[Keelano12]

The last week or so black lines started appearing on the screen and then increased to a few and then yesterday the screen went black and although it still vibrates it won't reset and cannot see anything on the screen. It apparently syncs to my phone but haven't been wearing it so only thing that has synced is that the battery is full. 

Have only had the Fitbit since Christmas so a few months and was wondering if you could give a solution to this problem. 

Cheers

Mine  started  a couple of weeks ago. Totally black  now. It  vibrate  and  sync  but nothing  on  the  screen. Tried  restart  but  still  nothing

The exact same thing happened to me ... Black lines a few days ago now a completely black screen.... And I've had this device only a few months....
