Hitachi 55inch projection tv with blue shadow.

The tv has a blue shadow about 80% of the time. Any ideas???

    I also a have a big blue blotch that takes up at least half the screen. It's always there but is quite noticeable in dark scenes or when the channel is changed and completely goes black until the next channel is received.



    I thought it might have to do with my Dish satellite that I got when I moved into a new home and I didn't have satellite where the tv was before.



    Any suggestions?

TV shows large red spot in middle of tv when dark show are on, you can see it more.  Now blue spots on upper right side too.  Spend way to much on this tv to have these kinds of problems only after 3 yrs.

PROJECTION TV HITACHI ULTRAVISION COLOR CONVERGENCE PROBLEM


it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

Blue and red shadows on screen


This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.
