I've looked this up and some CRT monitors, when they emit a high-pitched noise (especially when you bring up an almost completely white screen) indicates something is deteriorating or somewhat detached from the inside of it.
Was going to ask is this an indication that's it's becoming more harmful to human health? I've read CRT monitors and TV's let out some level of radiation. The further back you go in time, the more harmful the CRTs are, but would this high-pitch be an indication that the CRT is possibly more harmful to be around now?
