I recently bought a 27 inch curved samsung smart TV which I am really pleased about, however sometimes when I turn it on in the background i can hear a ticking noise coming from the TV. it sounds almost like a second hand ticking on a clock and im not sure what it is. the tv works fine im just not sure whether i should be concerned about it. I have only heard it whilst using one of the hdmi ports via a playstation 4, and if i hear it and change the source to tv, then back to the hdmi the sound stops.
so if anyone can give me any idea of what it is it would be much appreciated
