No video picture

I have a Syncmaster 710N which also constantly displays the "non optimum mode 1280 x 1024" msg. I have tried to connect the monitor to a system that had this display setting determined - no go. I then hooked up another system with a separate graphics card (the previous one had onboard graphics) with the same result. I have also referred to the troubleshooting guide in the manual -again a no go. Yet the LCD shows the pre-test screen OK but then returns to the infamous "non- optimum...." msg. I read somewhere that if the LCD displays this message continuously then a PCB will need to be replaced in the monitor. I was looking for some kind of reset button somewhere and have almost reached the point of throwing the "piece of ****" in the bin only to keep reminding myself that there must be a quick fix for this. I did have a glimmer of hope when I unplugged and replugged the monitor in and the display momentarily came up only to revert to black in a few seconds. Any suggestions would be most welcome.

My SAMSUNG 715v 17" LCD Monitor will only display 1280 x 1024 VIDEO RESOLUTION RECOMMENDED. even if i tried using another monitor just to adjust the desired resolution, after installing the SAMSUNG 715v, still it won't work. Before this problem goes on steady like this, it has been occurring intermittent in such a manner that it will display normally a couple of minutes then suddenly it will BLANK out and display the 1280 X 1024 VIDEO RESOLUTION..... msg. Now it totally won't display normally - just the Video Resolution msg. Is their any solution to this problem?

The monitor goes off after working for some time. Then even if we reboot it wont work for some time. After some time it works as normal.
