A new from the factory E420 came with a dim backlight. After trouble-shooting and finding the problem to be intermittent, the solution had to do with the routing of the lcd cable to the display plug under the keyboard and bezel shield. By pressing on that area the dim display would blink from bright to dim. By untaping the cable and backing it off to the left and retaping the intermittent display problem was corrected.
