Have a (3) inch long by .5 inch wide vertical "squiggle" shadow in back of 22" Dell LCD screen on bench. Much like a liquid dribble (spillage) would make. NO dead pixels or back light problems. Just need to get into monitor enclosure and clean up what is causing "dribble" shadow mark. Don't see any screws. Figure it must be a press fit interlock assembly but can't find starting point to disassemble. Don't have Tech reference manual.
Any help would be appreciated. Thanks !!
