Hi ! Have you tried connecting your device to iTunes ? Does it appear connected ? If it does, try restoring it. Mabe on a mac (on which restoring goes deeper). If it doesnt, start by replacing your battery. Your battery may be dead. Then, as a last hope, try & replace the display. You will find these parts and step-by-step guides to replace it yourself easily. Hoping to have helped you !
