check the vga cable which get loose connection then the signal from pc not recognized.

The monitor keeps flashing on and off? Or does your system keeps trying to reboot which causes the monitor to go on and off. Does the screen turn Blue before it goes off?

check your video cable ends for bent pins or debris, then make certain that they are plugged in straight and tight.

contact service center as its a manufacturing default and dont try to fix your self i m sure they will help u bye t.c

To find out where the problem is, you will have to try this monitor with another PC or try another monitor with this PC first to narrow down the problem.
Please post back after what you find out so we can help you further.
