Re: new flat screen monitor humming noise

This could well be your refresh rate. Move your mouse pointer over any blank area of the screen and right click. Highlight and click on properties.Click on the settings tab, then on advanced then on to the monitor tab. You should see a setting for refresh rate eg. 75 Hertz. Change the refresh rate and the noise should disappear.

View sonic computer screen was dropped and now when you turn it on the picture comes on and then it emits a high pitched sound and turns off. any suggestions?

Sounds like you may have broke at least one of the lamps . The high pitch sound you are hearing is the high voltage that goes to it .

Computer monitor may have stopped working due to exposure to cold temperatures. It will display for up to ten seconds all while a high pitched humming noise begins which then leads to the monitor shutting...

This means a high voltage problem. At most of these kind of problems the humidity is the reason for the problem. Keep the monitor at a warm and dry area for a period of time and try again. Don't keep the monitor power on for long periods while the noise is active, because this will damage the electronics.

With a piece of wood or plastic hit the flyback with the monitor turned on. If you note some change in the noise. Replace the flyback.
Normally, it is the cause of the noise.

Warning: High Voltage!! Do at your own risk!!!!!!

I am experiencing a high pitched buzzing noise coming from the dell monitor #cn-0p0151-64180-3a5-3642

CRT monitors and TVs do this after some time. It is caused by high frequency alternating fields - think transformer - when things get old and loosen up enough to vibrate.

The good news is that it is time to upgrade to a modern flat screen monitor, and this will be cheaper than repairs on your old tube.

Monitor Goes black, or flickers on and off

The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

Monitor making humming noise

First try moving speakers away from monitor a bit. Some speakers magnets actually reduce the life span off monitor. I hope I am wrong but usually a high pitch whine is the High voltage Transformer. Costs more than the monitor. All you can do is continue use till it goes. Speakers usually deteriorate the tube itself. HVT are just one of those parts that go due to use. Hope it gives you more enjoyment before it goes. Good luck and try to have a good day.

My Moniter won't work!

That high pitched sound in one way is a very good thing. It pretty much points out the source of the problem itself. That is more than likely either a blown capacitor or transformer on the power source inside the monitor. I would rule out the power inverter for the LCD backlight because the power light will not turn on either. I have found that Samsung is very good with their repairs, and if it is a somewhat recent model they should be able to get it drop ship repaired with little expense. That can be an inconvenience, and if you do decide to replace the monitor altogether, please be eco-conscious and have the old screen either donated to a goodwill organization where scavengers like me will buy it for raw parts, or to an electronics recycling center. E-Waste is becoming a very large problem and LCDs and flat screens are a hefty piece of it.

High pitch sound being emitted

It could be a harmonic noise caused by dust inside the monitor. If you are qualified (brave enough) to remove the back cover, blow the entire inside of the monitor out with compressed air (carefully) that may help. It could also be the flyback transformer. In that case, you would have to have the transformer replaced (I wouldn't recommend doing it yourself unless you are a TV technican as the CRT can contain a static charge of 14,000-25,000 volts- even when unplugged)
