How can I fix my LCD on my Daewoo FRS5021WAL?

My side by side fridge/freezer is 4 years old but has worked perfectly well until the weekend. After suffering hurricane storms in the middle of France it resulted in the loss of electricity for over 10hrs. Once restored again my FF was working. However through the night the power would come on and go off over a period of another 12hrs. When finally everything had settled I noticed the lights on my LCD were not on and yet I could here the motor running on the fridge/freezer and also the internal lights in both parts were on. Looking at the Daewoo website this model no longer appears on their product range so what can I do. Also is it possible that the cut in electricity is actually the cause of my problem as I want to try and claim through the house insurance along with other damaged I have experienced through the hurricane. Thank you in advance.
