\015 I have an Apple 20" Cinema Display LCD monitor that puts out a high pitched sound. I've lost some high end hearing and was testing it next to a G4 tower with loud fans so I didn't hear it but the person I sold it to did (his Mac Mini is nearly silent) and is returning the monitor to me. He says the noise gets less loud as the monitor warms up but never goes away. Is there anything cost-effective that I can do to make that noise go away? He also says there's one dead or "stuck" pixel that I did not see but he says shows up against a black screen. I saw something while I was search online for info about the noise that suggested there is a way to "unstick" a pixel, so if you have any such info that would be nice too. Thanks! -- Dan\015
