This is a convergence issue. Have you tried going thru the convergence touch-up thru the menu?. If you have and it does not cure your problem, the convergence ic flat packs have to be replaced. The average repair is around $200-400.

My hitachi big screen has red shadows on picture how do i fix it


What you described sounds like a convergence problem. When convergence has failed the colors will commonly look 3D,warped, etc. This tips page here on Fixya has more details.

Red shadow around every image


call up the menu and look to see if words have red or 3d effect---if this is so, suspect you have a convergence problem; the set should also have a option for adjusting the convergence---some just give you a cross in the middle of the screen---if red or blue will not adjust either up/down--left/right you have a bad convergence IC----The Hitachi sets all use two IC's and Usually this repair can be done in your home----I do a lot of them here in the San Diego area where I live----have done over a hundred in the last year on all brands of sets. If you know someone who knows how to solder etc, you can (get me model number) buy both the convergence IC's on Ebay for under 15 dollars plus shipping; some internet places offer a kit with the IC and whatever other parts might be needed; usually this is a waste as most of the time only the IC's and maybe one or two resistors around them are gone.
