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.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.
I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.
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. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
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.
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.
The problem on your monitor is a bad power supply. We you can solder you should be able to repair it. If you check our site at : www.ccl-la.com/badcaps.htm We have a monitor repair section with dis-assembly guides and repair procedures. I will post a Hanns-g guide tonight. This will show how to open and repair the monitor. We also have a repair parts kit available. If you don't want to do the repair yourself then we can do it for you, just email me if you have questions or wan tus to do the repair for ou.

No direct experience of this specific monitor, but LCD monitors in general seem to be susceptible to power supply failure due to the relatively cheap capacitors they use and the high working temperatures.
Turn it off, leave it for an hour or two, then take off the cover and look for bulged or leaking cap's on the power supply board. If the tops are not flat, they're probably duff, and need replacing with equivalent spec ones. Probably 105'C high temp - I got 105'C 470uF 35V ones for my monitor from Ebay at about a fiver for a pack of ten.
