Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Try this connected to another computer or laptop, see if the same issue arises. If it does not, suspect graphics card / chip problems. Reseat the Graphics card and reconnect monitor making sure all connections are tight.

Boot to F8 (safe mode) with monitor attached to the original computer, select VGA mode and see if that cures the problem.

If the monitor works on the other laptop or computer, then the issue lies in a faulty graphics card (assuming everyting else is ok on the computer).

If it does not, then you have an issue with the monitor.

this works for Dell monitors with a similar problem: shut down, turn off monitor and pc, turn off at wall socket, and remove power plugs from wall socket. wait about 30 seconds. plug back in, turn on, and all should be well? I have used this 3 times on a Dell PC with a Viewsonic monitor.

PLS MONITOR SERVIC MANUAL READ & LARN THEN CONFIGURE YOUR LAPTOP.

Unplug it from the mains, then try again. Does the screen show any sign of like (e.g. startup logo)?
Does the screen work on another computer?
Is the signal cable properly connected at both ends?
Does the PC work ok on another screen.
If still no joy, new ones are cheap - get a nice big one.

Hi, it's now the driver for your lcd display that you need but the display driver for your video graphic adapter
