Screen does not go 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.

Your monitor have board problem.Need for repair and troubleshoot.Maybe a deffective power supply.

this is a common problem with the capacitor, try opening your monitor and see if there is a capacitor swalow like gonna blow... the capacitor has a form like a AA battery... if changing the capacitor the problem persist maybe is a problem with the board and you need to search if the board have continous power....

Replace the entire DAC board (board with power suplly going into it) for easiest solution.

If the button on monitor is blinking, it means your computer is either turned off or in standby mode (or in hybernation).
You should push the power button on your computer to restore it from standby (or hybernation).

i had the same problem now my monitor wont even turn on if i do that the power light just keeps blinking maybe its a sign of a dying monitor

Try put off Monitor uplug power cord and the VGA cord for 1min and reinsert and restart your PC.
