I own a Hitachi 42pd5200 plasma. I recently noticed a white feint vertical stripe on the right hand side of the screen when viewing dark scenes. Also to the right of the stripe the area from top to bottom [and left side of the screen] is much darker than the rest of the screen. When using the screen wipe function [white screen] the same areas have a slight pink tinge to them. Can anyone explain why this is? My screen is just under a year old and has been calibrated using dv essentials so contrast and brightness are not set too high. I may call an authorized hitachi engineer to confirm fault and get a replacement.
