I remember always hearing that high-pitched sound when a TV was on, and wondering why my parents couldn't hear it. It would be many years later that I found out what it was. The thing is, I got so used to the idea that TV screens made that sound, that now I imagine I hear it even on modern LCD TVs, which don't make that sound.,(reply>), I think I have tinnitus at that frequency but I only hear it when stuff like this reminds me about it. I have decent hearing though. The other night I noticed that my bedroom TV's backlight makes a slight noise when it's set to an even number but not an odd number.,(reply>), Its really kind of a placebo effect. You grow up hearing it and so you expect it to be there,(reply>), Isn’t it that you might just have tinnitus,(reply>), @Banana Either I have tinnitus or I can hear my phone's capacitors screaming in pain.,(reply>), if you put your ear to the back of an LCD monitor and move it around at some point you will probably hear a slight high pitched whine from a capacitor. Hell I can even hear my phone in a quite room if i put it to my ear haha
