Worth Fixing my Mondeo Radio cassette LCD Screen?

I have just bought a Mk2 Mondeo and the screen on the radio cassette LCD is broken. Is this worth repairing? ie taking old LCD screen out and changing or is it worth looking for a replacement unit instead. I'll be looking at second hand and am apprehensive that I may end up with a unit that may not work. If the screen is replaceable, any advice on how this can be done?
Any thoughts on this appreciated....
