Hi. My TV has suddenly (I think so anyway, or I'm going crazy) developed a weird issue where whenever sound is playing, there is an audible 'fuzzy/swishing' (hard to fully describe) noise behind it. It even happens with a key sound when I press the home button on my Roku remote or navigate around the device for example. When no sound is playing, ie a pause in dialogue, I can't hear the noise.
This only seems to have developed over the last few days as I'm sure I would have noticed this before as it's loud/audible enough to distract me. It seems to have coincided with plugging in my new Roku streaming stick, but it also does the same with a Fire Stick and on regular digital TV (UK), so I'm not sure that there's much of a connection there.
I have factory reset to no avail.
I'm well within my warranty term with the supplier, but was wondering if anyone had experienced similar before I consider getting in touch with them. Or am I going crazy and hearing something that's not there?
Thanks.
