Power light blinks but the screen is black and won't come on.

Try a different video card or disconnect the one you have in your PC and use the VGA monitor connection on the motherboard. If it works your video card is gone.

Firstly check the power cables nd VGA port is it proper or not nd then if this is proper then ur problem might be in RAM remove the ram and rub it with eraser nd insert it again nd check CMOS battery also ....u will surely get a positive result....

The monitor needs an internal eletronic repair. Do you have the the necessary anti static tools including soldering iron. If so I can help you with the repair, else take it to a pro.

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

This sounds as if you are using the hibernate feature in windows reboot it and reset the power options to hibernate never check the vid connection as well

It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.

Your minitors power supply is now damaged, probably from the power outage. I t will need to be repaired or replaced. Check the cost and benifits of both options and make a discision.
