Question about Hanns.G Corporation HW191D 19" LCD Monitor
I have tested both the power cord and the video cord on another monitor. I have also tested the monitor on another computer with the same results.
The most common cause of this type of display issues is a failure of the back light power supply. There are parts called capacitors that fail and this causes the power supply to not be able to put out the correct voltages to operate the monitor. You cn repair the monitor easily by replacing the bad capacitors on the power supply board. The old ones need to re desoldered and the new ones soldered back in place. You can get a kit of the proper capacitors to do the repair here:

internal power supply failure,the AC power supply that powers the backlight fails every time you turn it on. Unfortunatly electronic repair is costly, A new monitor is cheaper.

I have the same problem. I leave the computer on for awhile to warm up the screen. I don't know why, that seems to help. I turn off the screen on the bottom right and do that a couple of times. Behind the screen I unplug and plug and unplug and plug the screen in again. After it gets going, it works all day. But at night I like to turn off the computer to rest. So I have to do this every morning.

Your monitor has a power supply that is going out. if you can solder you should be able to do the repair yourself, it involves replacing a few parts but its not that hard to do. Go to our web site at: www.ccl-la.com/badcaps.htm and look at the pictures and repair guides. Open your monitor and replace any capacitors that look like the ones in the pictures and you should be back going. We have a repair guide for the HW173 monitor that should be very close to your model.
I hope this helps, if so please rate our solution.
