Yellow Vertical Line, Goes away with moving the hinges.

What had first started with the hinges getting loose on my MBP, led to a single yellow vertical line, I'd say 1px in width, running down my screen. If I supported the monitor, due to the weak hinges, the line would go away. I went about this 'fix' for several months before the screen all of a sudden died.

I recently have replaced the display data cable, and the left I/O board. In that order, and upon installing the data cable and starting her up, I could see picture but no backlight.

Which led me to the left I/O board, which now installed I get picture, and backlight, But am still left with a yellow line that goes away when I move (the now tightened) hinges front to back.

I just don't want this to regress into the monitor going completely out again....

I've purchased an LED driver board as well, in case the I/O board didn't fix the backlight issue.

Where should I go from here?
