Samsung American fridge freezer

[daved01]

Hi I have an american fridge freezer model RS53K4400SA s/n 051x4ebha00993m bought from curry a couple of years ago. It has developed a fault No lights no display no chill freeze or water. If switched off for a short period I can hear something power up when switched back on all fuses are fine and the light (LMP1) on one of the pcbs lights for a second before going out.
Help appreciated
Dave
