Macbook and T220HD (22 display). 1680x1050 doesnt work anymore !

Hi! I have a macbook with a 22 inches external display (samsung t220hd). It was working fine for 9 months but i have a problem now... Last week i get my adapter (minidvi to vga) to other display to see a movie... but when i plugged it again at home... it doesnt worked fine.
The macbook doesnt detect the screen like "syncmaster", now it says "Screen" and i cant choose the optimal mode in resolution menu (1680x1050). I fully erased the hd and reinstalled OSX and nothing...
I have the minidvi to dvi too, but it doesnt work in the dvi port or the hdmi port.
Can someone help me?
Thanks a lot !

Maybe. Could be the heads bouncing against the platters - could be the optical drive. Best to take your machine to your local Apple Store and have them diagnose the problem. They can tell you if your data is salvageable.
In the future - make certain that you have one, if not more, backups - https://discussions.apple.com/docs/DOC-3045.
