    Hanns-G HC194D with Dell D Series Docking Station. I believe this to be a driver issue between the Lattitude and the Docking Station, but uncertain as the issue resolves once the monitor is recognized in BIOS.

Dark Screen, unreadable. Power Led Lights. No noticle sounds.


If you are going to DIY repair, please read below and look at the pictures of failed SAMSUNG monitors (bad caps with bulging tops)
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.

Screen turns black and blue LED is blinking


Sounds like the monitor is being made to show a resolution it does not support. Check the available resolutions the monitor supports and then check what resolution the video card is giving, if it not compatable, you get the black and blue screens.

For the video card, right click on the desktop in a an empty area and choose properties > settings > your resolution from the card will be there. Now from there click on advanced > click on monitor and look at the monitor settings. Make sure the box is checked to hide modes the monitor cannot display. Now click on the adapter tab and click below on all modes. This is the list of all modes that both the monitor and the video card argree on. Make sure the settings in your game match one of these and you should be good to go.

Monitor will not turn on


Unless you recently installed new video or monitor drivers, it sounds like either bad cabling to your computer (check the cables?) or the ribbon cable inside the LCD monitor has come unseated.

The unseated ribbon cable problem is more common if you recently moved the monitor or dropped it a bit. You can open the back of the LCD monitor (unplug it first of course) and check to make sure the signal ribbon is seated properly, this is a common problem.

Good luck...
