Question about Hitachi 50UX57B 50" Rear Projection Television
Hi, Try the auto convergence or auto focus to eliminate the problem, if this does not work, you may have to get the TV repaired, the common problem are the power amplifiers that correct the color convergence, that is why you get color shades or ghosts in the images.

If colors are skewed and will not adjust in the customer menu---you have a CONVERGENCE circuit problem.
This model (KP-51WS500) uses two of the STK-392-560 convergence IC chips. I just got home from fixing a similar model with the same problem.
Parts cost on Ebay for the chips and such is going to be less than 30 dollars total. Shops are going to get 300 or more for this kind of repair---and some will not do it in your home---the repair takes about an hour--I have done hundreds of them here in people's homes.
If you have questions or need advice, reply to this posting and I will try to help.
