Nissan Tino control screen?

The central screen on my 04 model through which you control ventilation, audio, rear camera and on board computer has blacked out. Previously there had been no issue, parked in Homebase car park, got back in hasn't come on since.
None of the above are now working other than the ventilation as it was at the point I had turned off the engine.
Anybody got any ideas on what has happened and how to fix it. I have checked all the fuses which appear ok
