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.

Red, green and blue colors don't match up on screen.


Please replace convergence out ICs (usually two) in TV.
If it is Hitachi 43UWX10B then its convergence out ICs are available in Part Store
Thanks.

Hitachi has had problems with their light engines. Very expensive. Contact Hitachi as they may give you consideration even if this is out of warranty.

Red and Green colors do no line up


It was most likely the convergence amplifiers. If you look up "convergence amplifier" on this site or google you will find lots of information. The part number(s) will be something like STK392-110.

I recently helped a friend repair this problem. If you are comfortable soldering it won't be too bad.

Hitachi 52 projection tv


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
