Every day now, for about a year i think, i have been hearing this BLOODY HIGH PITCHED sound while sitting at my computer around late afternoon early evening. I hear it in my family room (located half underground half above). I have a TV, a computer, a stereo, a phew lights, game systems and a phone down here for electronics. It lasts for a bout 10 seconds. Does anyone have a guess as to what this is?
If you need more info as to what I have then i can provide. I dont really understand what it could be. Am i hearing things???? when ever i bring someone over and it starts no one really says anything. It kinda sounds like the remote to my old tv when you press the tune and power button but its a lot louder and its more high pitched. Plus in order to get the sound you have to be physically pressing the buttons. Could it be my CD rom drive??? It doesnt normally make sounds like that and i dont even have a CD in the drive!
I am going to see if i can find out if it happens at a particular time of day. If need be if i am not able to answer it then i will record it. no im not kidding i dont know what it could be. I dont think anything i have could make a sound like that cause it peirces my ears and makes me shutter. ITS BLOODY HIGH PITCHED. Im not sure what frequency it is at but if i can find some frequency recordings on google i will tell you what frequency it is. Im just asking for help hard to do if u cant actully wittness it for yourself, but with the vast knowledge of ATS i hope that someone can help
There are a number of things that can cause a whiny high-pitched sound. It is almost always due to vibration of a component in the horizontal circuits, most often the flyback transformer or horizontal output transformer. Some times a good whack to the side sometimes temporarily fixes the problem. It will not get better over time only worse.
A service technician should be able to find the offending component and either replaces it, remount it, or add some material, which will stop the vibration. It may also stop if you simply run the monitor at a different resolution or refresh rate.
