Charge 3 unresponsive and won’t restart

[Ceri77]

Yesterday my charge 3 went a bit funny after I’d used it to log a walk. It kept vibrating and wouldn’t go off the screen for DND and sleep. Eventually I managed to get it back to showing the time.
Last night it became unresponsive and the screen stayed black. I plugged it in to charge with no response. I then tried to restart it and it worked but went to the same screen again - the one for DND. I restarted it again and it seemed fine although there was a fault line at the top and bottom of the display. 
This morning it is totally unresponsive again. It won’t sync. I’ve tried restarting it and it just does a long vibrate and stays blank.
What can I try now?
