Just got my display back from the repair shop with a new Digital board. The picture is terrible. The blacks seem to have serious shadows and muddy looking effect as well as everything else in the picture. Its as if there is a slight Andy Warhol effect to the picture. This certainly wasn't a problem before the repair or before the problem of needing a repair. When I play DVDs its not as noticeable as a regular cable signal but its there. How do I adjust this out of the picture? That is, if this is something I can do or is this a pro. calibration issue? Any help would be greatly appreciated.
