Moniter Making a High Pitched Noise

[Confusionz]

Dell 21" CRT

Bout a 4 year old moniter. And sometimes after i have had the moniter on for 7+ hours i hear a high pitched noise comin from the back. Not loud enough to really hear from another room or nothing. But able to hear it. If i jolt my moniter it goes away and somtimes stays away for a few hours. If i turn off the moniter it goes away... Anyone know whats happenin??

Sry if this isn't the right forums.

I get that same problem, except its with a emachine monitor. When it happens i just change the screen resolution. Lately i got tired of it so i just kept it at a slightly larger screen res. See if that stops the noise.

My LG Studioworks 995E 19" CRT monitor makes high pitched noise occasionally

The way i stop it is by turning the monitor off then on again

Sometimes monitors squeak because of the refresh rate the monitor is set to

thats a common problem with a lot of CRT systems, ive had a few televisions that have done it and have heard about many monitors doing it.... i found this http://www.pcguide.com/ts/x/comp/crt/failWhine-c.html, hope it helps if not, get some louder fans for your system
