Try it with another PC, check all the pins on the cable to make sure it is not the video card paroblem. Post back what you find before taking it apart.

If you are going to DIY and have proper tools and know safety precaution then please read on:
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 ACER 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.

SOURCE: moniter is black but has power

right click your desktop (when you can see it) and go to properties. Click the screen saver tab, CLick power button change the setting next to turn off monitor to Never. It sounds like the monitor is going into a sleep mode and not coming back out of it. Some monitors have this issue.

What you should try at this point is shut everything down, Unplug your desktop, hook it back up to tour moniter and boot. If you now get a picture, go to your device manger and click on display adaptors. If you have more than one selection. choose your monitor. Let me know if this works.

I suspect your computers power setting are turning off the monitor and not reactivating it (waking up) I would suggest attempting to change your power setting to never turn off monitor and see if that fixes the problem.

Please let me know if that works if not I can go over a few trouble shooting steps with you.

Thanks

My moniter says no signsl but the windows is working and i checked the moniter to my laptop and it works fine


Believe it or not but theirs an order in witch you should connect up a compute,r but first make sure that there is only 1 VGA port ie (monitor socket) on the back of it. But if theirs 2 then try the other one.
Other than that try this:
Unplug EVERYTHING! even the power leads from the back of the monitor & pc.
1.Press the power button on pc & monitor to flash out any power left in them.
2.plug in & tighten the VGA cable to the pc then to the monitor if required.
3.plug in all other peripherals ie USB / MOUSE / KEYBOARD etc...
4.plug in the power supply to the monitor then the pc.
4.Switch on the power supply to the monitor first then the pc.
5.Switch on the monitor by it's power button then the pc right after it.

I NEED HELP PLEASE!!!!!!! PROVIEW 19" MONITER.


Does the led on front of the monitor stay blue or does it become amber ?
If it becomes amber, then you are not getting a signal.
No harm in trying this : You can try to see if it is a contact problem.
With the monitor unplugged.
Use a small paper clip to run in and out of the blue vga plug holes a few times each to make sure they are not plugged or gummed up.
If that doesn't help and you know that your video cord is good, then I am afraid to say that more than likely there is a problem with yor video card.

If it stays blue then the signal is there but the screen isn't fully lighting up, leading to a failing power-inverter board or a bad bulb.
