r/crt 12 Posted by12 days ago = Huge Sylvania tv/dvd/vhs combo I found. It works. Makes a faint high pitch ringing. Anyone in the Los Angels area wanna buy it? = 100% Upvoted level 1 High pitched noise is completely normal for SD CRT TVs. Some mensen can't hear it because it is at the very top of human hearing 5 level 2 I'm closing in on 50 and can still hear this. I remember walking into work early in the morning when we all had CRT computer monitors and I could immediately tell if someone else was in the het bouwen van workingjust from the high pitch whine of the CRTLOL 2
