cropped screen, brightness

Hi guys this is a hard one.
I have a laptop sony vaio vgn-ns100e Win 7 64
This is my problem when i turn brightness down in PC brightness goes up and when i turn it up the screen starts to dim until screen gets comply black.
Also there is a black area in at the right of the screen.
On the bottom i see the upper part of the screen.

Now this is what i have done so far.
1.Test video card with Video Memory stress Test v1.7.
2.cheeked original drives & also DRPSu11.8.
3.Got a new inverter.
4.cheeked lcd cable on motherboard & screen.

observations
1.vaio logo is not visible wile boot.
2.connected to monitor, works fine.
3.Tried booting trinity rescue kit, black screen.
other ideas?
Thanks
Here are some pics of what I mean.

Fiddle with the display settings in the individual games or try changing the screen resolution on your monitor
