LCD Monitor Buzzing Noise

Hello,

I noticed that my monitor has been buzzing lately. It's not easy to hear, it's a lot like the ringing in your ears when you're going to sleep on a quiet night. But I finally realized that it was not my ears and the monitor when I linked white screens with a higher buzz. When I actually put my ear near the screen, the noise is very apparent, and I would be able to record it if I had a mic.

It gets annoying and I can see it leading to headaches. Does anyone know how to fix this? The refresh rate is fine (60Hz)...It is a little old (1999-2000?). I didn't realize this things had a lifespan.

Everything looks fine, and it's working fine, but the noise is really annoying! Any help would be appreciated.

Thank you in advance!

The inverter for the backlight is probably causing this, or the backlight itself. You should be bale to get inverters cheaply (they are comparable to the starters used for fluorescent lamps, and they age).

The buzzing is probably a transformer or other component that has not aged well and given how old the monitor is, it may be time to replace it.  New ones cost don't that much these days.

Do you think that might be a replaceable part?

its very doubtful its a replaceable part most lcds and even newer crt monitors dont have replacable parts.

For some reason I didn't think LCD's had lights.

They're called cold cathode tubes.  If you feel up to the task, here's a guide to changing the inverter or backlight: http://www.inventgeek.com/Projects/shorts/overview.aspx
