Make sure the power cable is not loose, causing the light blinking.

I don't believe this monitor has speakers.

Connect the monitor to a different computer, to see if the monitor works at all.

Connect a different monitor to your computer, to see if your computer really is "sending" a video-signal through the "data" cable. If not, then either the data-cable or the video-card inside the computer is faulty.

hi,
Before going to replace CCFL check the inverter of the CCFL. Normally the inverter get faulty. There is possibility that the winding of the high voltage transformer get shorted or its driver transistor may get faulty. check the same

Have you got the sound cable from the monitor plugged into the correct port on the sound card/chip?
Usually green in colour

There are two points here.
1. After the monitor turns black do you still see some activity of the PC? Like some noises of the HDD or the HDD light working. If yes then the problem could be with the monitor. (I doubt very much).
2. If no, then the problem could be with the Windows installation. If so the press F8 at boot up and from the black and white menu that you are taken to, select Last Good Boot up or words to that effect. Or you can even select Safe Mode. Let the PC boot up and then in the next phase you can let it boot normally.

Look for bad DC filter caps first.
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).

The PSU "power supply unit is taken on a lot of noise from the outlet. Can you tell us if you have it streight plugged into to a 120V AC outlet or is it plugged into a strip?

[u][b]LCD Monitor Shadow Effect[/b][/u]
This problem is best described as the LCD monitor "Shadow Effect".
The solution to this very simple. No software or hard ware changes required.
The cables that are connected to the LCD monitors are causing the problem. Its also called as electromagnetic noise or electrical noise.
[u][b]Solution: [/b][/u]Keep the two cables - (power cable and moitor display cable), that are connected to the LCD monitor as far away as possible with each other and also away from other electrical cables.
Thats it. Your shadow effect is fixed.
Thank you.

It means that the resolution of the windows is set too high for your monitor. You will have to find some better monitor to connect it to it, and then to lower the resolution, after that, it should be working just fine

Your monitor does not have sound capability. You will need external speakers.

it could be that the monitor is out of range. plug in an old crt monitor if it works go to display options (where you change your background) click on the settings tab and move the res. to 1024x768

the video card is too low on speed and memory. The lower end cards slow down the pc performance on videos and games.
Try to get a gig memory vid card at least

your resulition is set too high. to fix this you need to either change it on another screen if you have one or restart your computer into safe mode. usually in safe mode it will be on the lowest setting and you will have full access to change it from there.

Bring or call the place where you purchased it. This should be cover by warrenty (inside 2 months). Call the co. for a RMA, Replacement order. And talk to them about the details. This shouldn't be a big problem.
