I should ammend that these lines appear regardless of the source (digital cable, dvd player, video game system, etc.)
LCD HDTV Question
In dark scenes/parts of movies and tv shows on my LCD TV screen, there are lines of darkness slightly darker than the shadow or intended darkness. They make squares on the screen. I was wondering if this is normal or if the unit has been damaged? These squares do not show when there is color or light present, only in the parts that should be purely dark.
