Fix Message and Odometer Screen Displays

I have recently acquired a 2008 S-Type but after a few weeks the Message Center and Odometer screens have stopped displaying any text or other information. They do however remain back lit. For a couple of weeks the were intermittent in that they would both come and go. I have tried a few remedies that I have found on-line but without success. Any suggestion would be appreciated or do I need to replace. A terrifying thought $$$
