Hello,

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:

SOURCE: HANNS-G MONITOR BLACK SCREEN JUST FLICKERS

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.

Hello Joe,

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.

One day it went black, if I turn it off then on I can see a perfect picture for half a second


If this is a LCD monitor, most likely the invertor or the bulb is not working correctly. If you shine a flashlight at the monitor you should be able to see the image. What has happened is the back light is not lit to display the image. If you are handy at repairing electronics you can swap invertor and bulb from the other monitor if they are the same model and size. It may require some soldiering though.

Flashing green led on my hanns-g HX191D


Try it on another PC fIrst.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Hanns-g 19" HX191d monitor blank screen. Power led is intermittent flashing green. Does not show 'no signal' when powered up alone. Has this monitor died or is there a way to fix it?


Hello,

This type of issues is caused by parts called capacitors that have failed and are keeping the power supply from starting up correctly. You can rebuild the power supply board by replacing the bad capacitors and this will bring the monitor back to full working order. Here is a link to information showing what parts need to be replaced with pictures and parts list.
