Charge 2 dead screen, no power, one line on screen when restarted

[Hellosarah]

I have tried restarting as per previous posts. There are no lights flashing on the reverse despite it being charged up. The device vibrates as the line moves across the screen when pressing and holding the side button. Any ideas? It’s two years old and was a present so can’t return to retailer 😞
