High pitched noise coming from my Sony monitor

[zwoiks]

I have a gdm-f520 sony trinitron monitor and it produces a very high pitched sound. It comes on after I power it on for the first time after it's been off for the night. It typically comes on after 5-10 minutes of it being powered on and it goes away after a couple of minutes. Anyone have this problem also? If so, what was the cause?

is it new? how long has this been happenin for?

have you recently wet, electrocuted, burnt or severely beaten it?

I've had it for a little over 6 weeks now. The noise was first noticed a few weeks ago.

no, no, no, and no

My 21" Dell Trinitron did that exact thing for a few months, then quit.

My 24" Sony has never done that.

I have no idea what causes it. It didn't stress me out too much, because the sound always went away after the screen warmed up.

My 200es SOny has allways done something similar to that. Except mines not really high pitched, more of a bassy short hum, and it only lasts for about, i'm guessing 15 or so seconds....I allways though it was the caps in the CRT warming up....

I had this happen on a 15 inch sony monitor before, I changed the refresh rate, and the high pitch sound was gone. Try this on yours, maybe it works, I think it might be radio interference?

A high pitched whine is not necessarily an indication that the monitor is dying. 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. This is why a good wack to the side sometimes temporarily fixes the problem. It will not get better over time only worse. I do not recommend you attempt to fix this yourself, unless you are trained and very comfortable working with extremely high voltages.

A service technician should be able to find the offending component and either replace 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. If the monitor is under warranty I suggest you send it back for a replacement.

Good Luck

I would just hit the monitor on the side until it stops screaming!
