Windows 7: External monitor turning off on it's own after a few seconds

External monitor turning off on it's own after a few seconds

I am using an external monitor LG Flatron W2246S. It has been working fine up until today.

When I set it up, the screen shows for about 3 seconds then goes black. The monitor is still switched on. I've run trouble shooting and found nothing. I've disconnected and reconnected and the problem persists.

Please help.

What cable are you using to connect the monitor to the PC?

An I/F cable

UPDATE: Tried a different monitor using the same I/F cable and it worked fine. I would like to get the more expensive monitor working.
