My kindle screen is burnt?

My screen has the "needs charging" screen burnt on it. It doesn't change and I have charged it, the orange lift comes up to say it is charging and when it goes green it charged. The power button appears to be working as the green light flashes. I have pressed every button but the screen is still stuck on the needs charging screen. I think it is because I didn't use it for a while, do it may have been like that for a few months.
