Use the up/down arrows on the bottom right. Though you may think they are volume, it actually is for contrast when the phone is on-hook.

The common thing on this style of phone is the silver ribbon cable that connects the display to the main circuit board comes loose after being dropped or knocked around and needs to be reinserted. You will need to open up the phone to do this. If this is not the solution then you will either need to purchase a used phone, send it in for repair or use another phone to take parts from.
