has my fridge/freezer died and can i fix it?

I have a Fridge Freezer upright may be called Pentan!?
The Fridge section was building up water on the fridge floor under the two food trays. Also ice used to form on he back of the fridge I regularly had to mop it up.
Until recently it stayed cold but last night the fridge light went out. It lost it's coldness and the freezer section defrosted. It had been getting very heavily iced recently. There is also a little water on the kitchen flr.

Has my fridge died or can it be repaired?
