NOISE IN MONITOR


Hello

Something you can try is to have a look at the frequency of the monitor. Right click on the desktop, propperties and have a look at the settings.

It is usually the wrong frequency which result in a noise.

Hope this can be helpful.

Kind regards

How do i turn off the high pitched frequency noise


If what we are talking about here an old model of monitor that has a bulky back, the high pitched frequency is caused by other electronic devices such as your speakers.

- Relocate your speakers away from the monitor
- do a factory reset on all settings on the monitor or if possible, do a degauss.

My hp w2007 moniter keeps going black after about 10 mins. of idle .turned off screensaver because i want moniter to stay on but it doesnt.


Where you go to select "no" screen saver, there should be a "Power Settings" button. Press this and in there you can set the power save feature to "never" switch off monitor. Hope this helps. Ian.

KDS Moniter


Have you checked your video card or adapter?
Check the settings on the monitor itself.
If you didn't find the problem go into system properties (windows logo + pause)/hardware/device manager. Expand monitor/right click and see if your new monitor is listed. Is there a yellow or red symbol next to it? This would mean a problem, then right click symbol/properties and error will be shown.
Could be a memory issue.
Don't forget to try a "working monitor". This will narrow it down a bit.

Moniter stays blank


I used to repair LCD flat screen from Dell. I am not sure that my method might be applicable to your CRT monitor. Anyway this is how to examine what wrong with the monitor. You have to check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. In my case, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you
