How to fix blue screen followed by sound on Ender 3 Pro

Hello to all,
I am struggling to fix an error on my Ender 3 Pro.
Few days ago, my printer shows only blue screen followed by some error specific sound.

Here is the video that I recorded:

After some research I have found this video:

There is exactly the same sound produced by printer.

I thought this issue is caused by Thermistor, so when I checked it was pretty damaged and black. Today, I bought a new one and replaced.
I checked all of the connections with the motherboard and could not see anything which is not properly plugged in.

The current firmware is Ender-3 ProMarlin2.0.6HW4.2.2EuropeMultiLanguage downloaded from official homepage and upgraded two weeks ago.

I also tried to flash it again with renamed *.bin file but could not succeed.

Any help will be very appreciated.
