Some component might have loosen up on the circuit of your monitor! cleaning inside and resoldering loose components could fix your problem!

Push the button on the front that says menu. Within that menu you will find the brightness control. Use the other buttons to move through the different menu items until you get to Brightness. Once there push the menu button again and then adjust the brightness with the other buttons.

Adjusting Brightness on LG Flatorn Monitor

You cannot adjust the brightness with the key board. If the brightness control on the monitor is not working. It may due the defect of screen control on the flyback transformer. You have to replace the flyback transformer (FBT)

Monitor settings

Have you checked the actual board that has the buttons to see fi there is an issue there?

If you've found nothing there and still experience the issue, sounds to me like you might be looking at a bad micro.

Irritating display

This is a sure sign in CRT screens that it is on it's last hours of life. I saw this in one of my customer's screens and I told him it was probably dying, it died the next day. You could try opening the menu and hitting degausse or whatever it's called. That helps sometimes, but if this is doing this repeatedly, it means your screen is dying.

Is there still power to the monitor or is the screen just black? Do you hear any sort of sound when it goes black? Does the time the picture goes out vary or does it happen after say "X" minutes/hours everytime? Do you have any power saving software activated that would cause the monitor blank out? Check display properties? Sounds weird but have you checked for any viruses or spyrus nasties? If its hardware it could be many different things. Let me know what happens. Good Luck Tim
