At last I found the answer to my question.
The country is Poland, the city is Gdansk and the year is 1981.
In Gdansk, there were the black TV screens. People there began moving their television sets to the windows-with the screens pointed out to the street. They were sending a sign to one another, and the government. We, too, refuse to watch. We also reject your version of truth.

Not 100% sure, but here is something to look into. Hungary had a regime change in 1989, moving to a non-communist government. During the revolution, protests frequently occurred at state TV headquarters. Furthermore, this could be a very Hungarian thing to protest, as in 2018 these anti-state TV sentiments happened again.
