I would need the model number in order to help you out with the problem. Please respond to this post with your model number.
SOURCE: Hitachi 43FDX11B television Ghosting
I had the same problem on my Hitachi rear projection TV 53FDX20B made in Mexico. The blue convergence problem. Blue focus had shifted and appeared like a blue ghost image. I followed the step by step intructions from the fixya site. First Replaced the two STK 392-110 ICs and turned on the tv. No change. Then I went looking for the bad resistor. There was one resistor RK50 (2.7 ohm, 1Watt capacity) which is attached not right close to the printed circuit board surface but was well raised up from the board. The bands on the resistor were a little discolored. I replaced that one and turned on the tv. The convergence problem was solved. Thanks for the step by step instrucitons on your site.
SOURCE: hitachi 53fdx20b picture is red
This is a set first made in 2002. I have seen a few of them with too much red.
Most
likely what is wrong is the RED SCREEN CONTROL. It is located
behind the front grill assembly at the front of the set. Screws usually
secure it from the back on either side and then it pulls off--held by
pegs usually.
Behind it is an inspection plate with several
screws. Behind that is a BLACK block about 3 inches square with six
controls(everything is black) One row of three will be marked
FOCUS--stay away from those. The other row will be marked SCREEN.
With
a flashlight you will have to look closely at the two rows of
controls--they will have r,g,b marked next to them. (red, green, blue)
If you go to a Black and white program and the background is redish etc--take the set to a unused Video input
and after you locate the RED SCREEN CONTROL turn it slowly (less than
1/8 of a turn) to the left---the idea is to adjust just until the
screen does not show red---on a blank input it should be black.
Double check it on a Black and White program and then if it was the problem the color should now be normal.
These
sets did have some problems with that Screen /Focus block going
bad--the entire block costs under 25 dollars and all the wires on the
back of it plug in; if you have to keep adjusting it over a short
period of time replace it or live with it.
I do this here for free so if this has helped you rate this solution as I do this here for Free.

The tv have a problems known as a convergence problems,it dead.The tv have colors R,G,B lines mis alignment,have colors shadows or 3D pictures.The tv convergence board,the 2 STK convergence ICS and some or all it resistors are dead.These parts,must be replaced to solved the tv convergence picture problems.The shop,will cost u $300-350 for parts and labors.
