Monitor is putting out a really annoying high tone

A couple of weeks ago, my monitor started randomly (?) putting out a very high 'beep'. Its not like a 'notification beep', but a monotonous long 'beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep', at a very high (all through your bones) tone. Sometimes the beep stops when I switch my browserwindows to a site with a differently colored background (so when its beeping at white, it will stop at black, and v.v.), but sometimes it just goes on all the time. I have no built in speakers, and the sound definitely doesnt come out of them, as its also there when my speakers are detached completely. I have thought of it being my soundcard, but my pc (not my screen) is on the floor now and i still hear the sound coming out of the monitor's direction, and it stops when i turn my monitor off. It's a pretty old (5+ yrs) monitor, so maybe thats the problem, but maybe you know what else might be up, and if theres a way for me to fix it. Thanks for you time.

Re: Monitor is putting out a really annoying high tone

Sounds like you have a capacitor going bad. All monitors make a noise, whether the human ear can usually hear it or not. If it has gotten rather loud, I'm afraid your monitor is on its last leg. White is a hard color for a monitor, because the electron gun inside has to fire on all pixels, and of course black is easiest because it is just blank. Some people I've talked to have had temporary relief or prolonged the life of their monitor by keeping it on lower resolution in order to make its job a bit easier. Besides that, there isn't too much you can do.

Hi there. I had the same problem months ago when I try to play high end games like Sims 3 my monitor goes into power saving mode. I tried to check every possible causes of the problem. It could be that your computer is overheating try to clean your computer and check if your fans still works. Second it could me your power supply malfunctioning, maybe it does not meet the required power to make your game work. Last cause is your video card malfunctioning, what I did is to just buy a new video card and it works.
If you do not have spare power supply or video card you can go to a computer repair shop for them to check the possible problem that causes it to go into power saving mode. It can also save you money before you can buy a new one.
Hope this helps, Have a good day!

I have a dell E153FP Flat panel monitor that just started flashing auto adjust mode, randomly. When I power down it doesn't do it for awhile then will start back up again. Help this it really annoying!

Can you use it?If you can the internal power supply might be going or the inverter board.One way to confirm this is listen closely to the monitor if you hear a sound almost like tin foil in the wind the internal power supply is going,if not you are good.However If you can go into the menu of the monitor try doing a factory reset.This may fix it.
good luck

Monitor loses power randomly.

Is your monitor a CRT or LCD type. For CRT type information follows. In most cases your simptoms indicate a problem with the High Voltage or blanking circuits. Caution the High voltage can be as much as 40,000 volts and even unplugged from the wall the picture tube can continue to hold voltage (enough to hurt you). Do you here a snapping sound from the back of the crt. If you do the high voltage is shorting out and the protection circuit is turning off the high voltage. If you do not here sparking another possible cause is a faulty capacitor in the protection circuit or the flyback (high voltage transformer). Unless you are educated in electronic circuit repair this one is probable beyond your curren knowledge level. You can try taking the back off and cleaning out all the dust, but remember to stay away from the red wire that goes to the picture tube. Use only non metal cleaning tools. Good Luck
