Acer V193HQ Monitor won't start, yellow light flashing

A 2008's Acer V193HQ screen started behaving as follow: I start my pc and one of the 2 screens (dual screen on a ATI 5770 HD) won't start, instead the yellow (stand-by) led starts flashing for quite a while until suddenly blue led turns blue and the screen starts. I already ruled out everything but the screen, so, it's the monitor. Some advice?

Hi if it's the monitor you would be better off just getting another monitor in my opinion. Unless the monitor is under warranty then have it fixed under the warranty.
