Samsung RB29FERNCSS refrigerator - two LEDs on the panel are flashing

After a power failure, it turned on and cools and freezes, but on the panel (3 buttons) the LEDs from the set temperatures flash and does not respond to the buttons. What could have happened?

Page 24 of the owner's manual - it doesn't hurt to think. The manual can always be downloaded from the manufacturer's website. Let's not clutter the forum with the obvious.

I love our forums for the mentoring tone and .... the lack of careful reading of the posts.
I wrote "LEDs are flashing for the set temperatures and does not respond to buttons "
Accordingly, the "polite" RTFM-style suggestion was of no use.

The buttons do not work, do not "spit" as before when pressing, the refrigerator is cooling and freezing, and the temperature LEDs blink happily. Further suggestions?

I also love but what can you do. Same A and ?, but no one is a fairy here, but everyone wants to have a given solution on a tray. The description implies nothing, we can guess. The diagnosis is visual inspection, measurements.
We start with the fact that the beam in the door could be damaged, the control module could suffer as a result of a temporary overvoltage (or at least the power was turned off). You can turn off the refrigerator for 10 minutes and check its operation after turning it on.
The refrigerator is not under warranty?

Unfortunately, after the warranty, and there is a sister, so access is difficult. I will ask her to turn off for 10 minutes, let's see if she can do anything. The beam should be ok. It happened after a power failure. I rather bet on the control module and they are for about 100 PLN. Before I buy, I am looking for a hint - maybe someone had such a fault. Is the replacement of the module associated with disassembling the door or is it enough to lift it from the outside?

Have you solved the problem? I have the same symptoms after a power outage.
Edit:
The solution to the problem is to hold down the Fridge and Freezer buttons simultaneously for >15 seconds.
