Why did my screen flash white and show a blue mark?

Why did my screen flash white and show a blue mark? I turned my calculator on and the screen flashed white with a blue dot on it. What's going on here? Is there any way that this can get fixed?

It sounds like it won't turn on otherwise? The link has some troubleshooting steps for not turning on in general.

Hope this helps!"
