[screen is just blank]

Can anyone help me with this problem? I turned on my printer after a couple months of non-use and got a blank screen. I cant do a reset or anything, unless theres a way that I dont know about. Any Advice is greatly appreciated.

[x or y switch problem]

So im not sure what happened with my 3d printer but i guess im not allowed to show add video to the forum. Apparently, the axis on the back right side will move  but the  connecting axis will barely move an inch as the pulley moves. I wish i knew the terminology to some of these components to clarify better. Ill take any help available.
