My monitor is giving a wheezing sound when switched on. What is the problem and how can it be rectified?

If it is pretty loud and then fades away, this is the degauss feature.  If it just makes a high frequency noise then you probably have the flyback transformer starting to go bad.  It will probably still last a while though.  They can run as high as 70 or so bucks.  The labor and time spent looking for the right part do not warrant repair.  buying a new monitor would be your best bet.

Your monitor isn't on or plugged in properly to the computer.

if its making a loud whurrrrring sound, like a hum in way that means your air input fans and/or power unit fan are clogged with dirt and the fan is straining, causing the noise.\n\nif you have a fan on your processor as well, check it.

Could be a bad monitor - sometimes that happens.\nOr there could be something that's causing interference such as a cell phone charging nearby, a fan running etc...

First: open the box and clean the inside, focusing on the fans.  Use a vacuum cleaner and don't forget the fan that's in the power supply.  DON'T open the power supply (that's dangerous, even if you've disconnected the power cord which you should do before opening your computer), just move the vacuum cleaner over the fan blades.  While you're at it, clean out the rest of your computer as well; be gentle as not to break anything.\n\nThen put the power cord back into the power supply, do NOT close the computer, and switch it on.  Is it more quiet now?  Congratulations!  Shut down your computer, remove the power cord again, close the computer, and plug the power cord back in.  You're done.\n\nIt's NOT quiet [enough] yet?  Listen closely to what is causing the noise.  Replace the culprit, or have it replaced by someone who knows about computers.  Fans aren't terribly expensive, and neither are power supplies.  (If it's a fan, and not the one in the power supply, you could try to put a VERY little bit of WD40 on the axis of that fan.  The axis is usually covered with a tiny sticker, which you'll need to remove.  The fresh oil usually makes it hard to put the sticker back on, and when you don't succeed it usually doesn't take long before the oil dries up.  You'll be back at square one again.  So replacing the fan is probably a better solution.)\n\nGood luck!

Try turning on the monitor, see if it is plugged in right.  If none of that works don't hit it with a sludge hammer, bring it into a computer store.

You're going to have to supply us with a lot more information - is it plugged in?  Is your computer on?  Do you have the right cable?  Has the monitor worked before with other PC's?  Have other monitors worked with that PC?

A faulty power supply on your monitor will cause this problem.  Have you had a power failure in the last week or so?  And high voltage spike or a brownout can damage your power supply for both your computer and your monitor.

Check that the monitor cable is correctly connected.\nIf it is, then get a new monitor from some place with a good returns policy - just in case the problem is with your graphics card!!

that sounds like a problem with your computer screen. the colors change when the monitor is about to stop working

Believe it or not, if that speaker is near your computer, your monitor or another electronic device, try moving it away from the other device.\n\nIt may be that you have RF (radio frequency) interference that is causing the problem.

The flyback transformer is cracked.\nFlybacks are expensive.\nGenerally, it's cheaper to get a new monitor unless it's like a 21" or something.\nOk, I am not going to say 100% that it's the flyback, sometimes the power supply can whine too, but that is rarely combined with a bad smell. I'd say about 95% it's the flyback.

Try degaussing..it is probably within the button on your monitor, set color etc.. when get to degauss push the button and it will remove static, worth a shot

try changing your refresh rate to stop that, sounds like you have the monitor plugged into a power strip so its not saving the settings

Your monitor hardware does not support 1152 by 864 resolution selected by you. Turn off your PC and restart it in Safe mode, select the earlier resolution and then restart it in normal mode, your problem will be recfified.

Sounds like it is from magnetic or electrical interference.\nMove away any electronic devices (non-computer related)\nFind the control buttons on the monitor and see if there is a degauss setting, run the degauss.

Well, you need to describe the noise better to help with the diagnosis.  \n\nBest idea without knowing more is to check your power supply for noise (120Hz hum).  Make sure that it is adequately filtered.  If it's a hiss, you may need a couple of small capacitors on the input to act as a low-pass filter
