This is the Pronto Support line. From there, they can tell you how to swap your unit/send in for repair. If not under warranty, it may cost you a bit to get a screen.

You might want to search for +replace +7000 +screen (for last 4 years) as there was once a link in one of these posts where you could order a screen. Screens may no longer be available but glasstops for screen may still be available. In this case, your only option will be Philips.
