I hear a little buzzing from the TV, and only from the top right front corner. From the back it's totally silent, and everywhere else, too.
What could this be? I searched a lot on the internet and found nothing relevant.
It's not so disturbing, but enough for me to think about a solution...
I can hear it clearly from about 2.5m/5feet, on a volume about 10 and under.
Could it be repaired or is it natural?
