Blinking Power Light and monitor will not come back 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.

Needs to got to monitor repairer.

This sounds like aa power supply problem. Pursue checking for the problem with the power supply.

power supply has blown. you need to replace the bad capacitors on it. common problem

Try taking on the back of the monitor and pulling the power plug all the way out of it for about five minutes and then plug it back in and restart the computer see if it solved it thanks

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

Try your monitor cable connections on both your pc and into your monitor.
Make sure they are TIGHT and level.

Also, it could be your video display card is faulty or your video display drivers are corrupt.

Try setting your desktop to a lower resolution, like 800x600 and see it that helps.

I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard

Hardware problem You need to take it to a shop or send it back to manufacturer.
