Your unit uses a Cathode Ray Tube (CRT) for each color.
Since you didn't say that it was a gradual change, I suspect the CRT filament has failed open rather than a slow death of internal emissions.

Considering the very high level of light asked of these CRTs, I am amazed they last as long as they do.

The replacement and almost certain necessity of initial alignment and color balance, this is beyond DIY possibility and is likely going to be fairly expensive.

After 5 years of use, the other CRTs are somewhat (if not a lot) degraded so don't be surprised when a tech advises replacing them all and I think it may not be a whole lot less expensive than replacing the set although looking at the specs for that set indicates it is not obsolete by any means.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

I have owned this model for 4 years now. 2 years ago this same thing happened to me. I think the repair man said the transformer went out and he replaced that. It has happened to me again so I will try and do this myself, and let you know if I succeed. This TV has been terrible, I will never buy hitachi again. If you ever use an hdmi cable the tv does very weird things like changes color or distorts for about 30 secs then goes back to normal. P.O.S.

This is a set first made in 2005. I have seen a few of them with too much red.

Most likely what was adjusted 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.
