Samsung SR-l629EV Display not working?

Hi, i have a samsung SR-L629EV fridge freezer, at the weekend (of all times) my wife accidently pressed 2 of the buttons on the digital display panel (top 2 i think) and the beeper sounded, since then the fridge has not been working correctly and the display has stopped working altogether, so no idea of the temp inside the fridge or freezer, however the freezer seems to be operating correctly and if i turn the unit off at the plug leave a second and turn on, the fridge seems to kick into life for about 8 hours (maybe its reached the correct temp but no way to tell).
Is there a way of getting the display to work again or anywhere i can get a new display panel as i believe it may be the cause of the problem.

Any ideas or help greatly appreciated!!!!
