Question about Hitachi Televison & Video
As you know this rear projection TV has 3 CRTs to produce colored picture and I'm afraid that CRTs got weak in result and causing incorrect / inappropriate colors as you mentioned above.
Red gun seems more weak then other green and blue guns.
you can slightly improve colors quality by adjusting Gain of all 3 CRTs but it requires expertise because you need to go in to service mode of TV. service manual has details about adjustment.
Please do not expect sharp colors performance from ten years old TV, what ever brand.

Firstly check if it is TV or set top box issue, by connecting a dvd player and try play something.
If still you face the same issue convergence is out...
This is a common failure with Hitachi sets. Actually, you were charged a little less than most - which usually runs around $400 to fix up the convergence system.
You could probably do the replacement by yourself.
First, go to the owners manual and make sure you have gone through the convergence set up. When pushing the magic focus button be sure that the set does inaugurate the convergence routine.
Your model has hundreds of parts listed at the www.partstore.com site, find the part number on the case of the convergence ICs and search for it. They cost around $30 to $50 each and there are two of them of the same part number (usually). They must be mounted with great care.
Let me know the status ..... Kevin.
