I have been trying to fix my gateway m675xl lcd. It had been all lines and garbled. I started to take apart the lcd thinking it was shot and after I played with the wire in the back, my display has magically come back to life...

but, now the screen is small. there is about 3 inches of black border on each side and 1 inch of border on the top and bottom. Any ideas how to fix this?? Thanks for any responses in advance.
