So I have started buying crt tvs again. I got them again because people have said how good the color look and the refresh rate. I actually grew up with a crt in my room and had no issues (this one was a Samsung if it matters). Recently though, I can hear a high pitched noise coming from my new crt tv. This is not the same tv I grew up with, it is a different one. It only has mono sound if that also could be an issue. Is it that it's a bad tv? We picked it up at an estate sale for free. Or am I just now capable of hearing the noise? Maybe it is becuase it has been a long time since I have used a crt?
