Hi, Im sorry to hear that, That woudl be also considered a power cut however small.
Please try one thing for me? Unplug your fridge for 30 full minutes to cause a reset of the internal control board.
Then you can plug it back in. This will let me know it the computer board inside simply glitched or actually was damaged by the that power blip.
If that restores normal operation Great, but if not please let me know so we can help you further;-)
In any case, I will stick with you until this is complete.
