Hi, I was wondering if anyone has a solution for my monitor problem...
My monitor is making very high pitched noises. At first I thought it was my ears however when I turn the monitor off the high pitched noise goes and when I turn the monitor on the high pitched noise appears. I have changed the refresh rate a number of times and this hasnt made a difference. I have a Dell E773c.
The noises will sometimes appear alot however sometimes it hardly happens.
There may be a simple solution to this so if there is one it woudl be great to hear it.
Then it is what I said above. You need plugs in your hears. It would have to be loud for me as I have Hearing aid. I would have heard it in the past as I used to dabble with TV's. It could last for some time but can be an irritant for sensitive hears
Basically, what woodchip is refering to is the mechanics of the transformer. They are not mechanical devices, but they do have laminated insulation. Sometimes, over a period of time, thermal stresses can cause the lamination to slightly deform...
The resultant high pitched whistle you hear is caused by a mechanical resonance being set up by the various electromagnetic gubbins that is knocking about.
Realisticlly, given the cost of monitors, repair isn't likely to be cost effective. A gentle tap might prove efficatious!
