Screen won’t turn on when plugged in just horizontal line-Charge 3

[Suebit1]

My charge 3 problems started one evening when it wouldn’t turn on when I turned my wrist I put it in charger and pushed button on side. It seemed to helped   But during that night it went crazy flashing and vibrating. Again I plugged it in and pushed button and left it die the rest of the night.  But since then it won’t do anything when not in charger won’t turn on. Tried to update but it can’t find the Charge 3. In the charger it is just the horizontal line or sometimes the smiley face. Can’t change clock face the phone can’t connect to it. My charge 3 is not that old. Help.
