I have a refrigerator Samsung RF28HDEDBSR/AA over the past year the power went off, now I can't get the display panel working again, it is blinking with code 5 - C , the fridge is cooling, I can get water but can't get the ice from ice dispenser and LED lights for water dispenser are on all the time - any suggestion? I have tried pressing top buttons, nothing works, unplugged for 5 min. and then plugged again, no help. Any advice , please...
