[rescue] LCD Screen Trouble

I've managed to salvage an LCD that has some issue with artifacts across 
the screen - they only appear when they cross two blurred vertical lines 
across the right side of the screen, and only with certain colors.  What 
also puzzles me is that the on-screen setup is not affected (unless I 
should trigger the defect, and it obliges to display what is under it).  
What I'm wanting to figure out is what's causing this particular defect, 
as my only guesses are the inverter or panel.

Console(where the vertical bars are):

Full-screen (triggering the most artifacts):

An image taken to highlight the artifacts(full screen):

Partial (only does the single bar):

Demonstration of color-dependent artifact(Warning: is large, see upper 
right corner of image):

Note that the artifacts stretch across the screen -  but only when 
crossing both vertical lines, and on certain colors.  As for testing, 
this happens independent of whatever is driving the display.
