Samsung FF SR2028CVW not cooling & freezing?

Hi can someone please tell me the following error code on my fridge freezer model SRC 2028CVW please.

The top digit of last 8 (on the fridge side) on digital display blinks. No other light or digits are displayed. No buttons on either side of teh digital display work.

The fridge freezer just stopped all of a sudden. Have tried switching it off now for 5 days bust still the same issue on plugging it back in. The light inside the fridge works but there is no cooling. The freezer is also not working.

Bought the fridge freezer in around 2004 from John Lewis.

what is required to fix the above issue?
