53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows

For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

Picture has shadows with different colors (red, yellow, green)

Sounds like the convergence needs adjustment. You can do this through the menu-follow the on screen instructions. The idea is to line up the red, green, & blue.

My picture just started having doubleimage like shadowing

your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

Blue shadows appear to be behind white objects

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.

Blue and Yellow shadows

Google "HItachi Convergence Circuit" and you will see that it is a very common problem. Looks like TV repair guys get $400 to fix it. The parts will set you back $15-$50 but there is some complicated soldering to do.

I am going to repair my own...but I have a lot of experience in soldering

Ultrascan hitachi 43" hd tv

What you're describing is convergence and the amps need to be replaced... IK04 and Ik05 are two STK392-110 and Hitachi suggests replacing them with the STK392-150's for greater reliability..
If you're not too capable in electronics this is one to leave for the professionals. But at least you can call around and ask what each shop charges for replacing the convergence amps in this unit...
Hope this helps.
