Samsung Syncmaster 753DFX display

My Samsung Syncmaster 753 DFX screen Shakes and Wobbles unusually. When switched on, it work nicely for say 5 minutes. Then the display starts stretching from the middle and suddenly the monitor shuts on and off continously. I tried switching off the monitor for sometime, and it does work nicely again for say 2-3 min, but then again the problem arises. This problem happens on BIOS screen, normal DOS screen, Windows, Linux everywhere. So it is not the driver's problem. Something to do with the hardware. If somebody has any information or might be able to help, please help me.

Sounds like the monitor is going out. If u have another system u can try it on i would try that first but it just sounds like ur monitor is on its last leg.
