We had been seeing some strange but rare issues on this monitor. It suddenly stopped working all togother. Now the green LED light on the front blinks and nothing is displayed. This monitor is connected to the HP Pavillion 1010n.
Is this a monitor problem or video card? I tried to swap monitors on our 2 PC's and neither of them worked. The mx705 did not work on an older Packard Bell PC and the HP Pavillion v50 did not work on the 1010n.
If the HP has onboard video but you have an add-on video card, remove the add-on and connect the monitor to the onboard vid. If it works you have a bad add-on video card. If it doesn't or you are already running on on-board video hook the mx705 up to a compatible HP. The older PB may be TOO old to handle it or not hve the correct drivers.

The first requirement is that you must have video coming from your PC, then you have to press and hold for more than 10 seconds the "MENU (OK)" botton, this must unlock the OSD controls of your monitor.
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
Since you have tried another monitor with your computer, then we can only assume that your LCD monitor had gone bad. If the light is green but you can't see anything on the screen, then most likely the backlight has gone bad. Unless you want to take the monitor apart, I would suggest buying a new monitor.
If the computer is attached properly and you get the flashing lights it is due to switch mode power supply being faulty, too expensive to fix I think you will find, never seems to be anything like just a fuse I'm afraid, modern worlds tells you its time for you next monitor..... do try to ensure it aint the pc by hooking laptop or something else to this unit, or hooking another monitor to your pc to be sure but I find power supply failure is normally how monitors leave this world...
Is the green flashing on the tower or the monitor?
If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.
Check for the power supply light at the back of the tower.
Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.
Then connect the cables and check if it is working.
Look the problem it may not your monitor it's your windows XP.
Let me guess you have a VGA/Svideo card. From prior experience I can tell you that dual output Nvidia cards will default to Svideo first, and then "adjust" your windows settings to do so every time even if a VGA monitor is re-connected (HIGHLY ANNOYING).
So if the last thing you see before nothing is the Windows XP boot screen, here's how to fix it.
Boot to safe mode
uninstall your video driver, reboot then reinstall.
You can substitute a system restore for uninstalling your drivers if you can remember when the monitor was last working.
This really really pissed me off when it happened to me.
