My Hitachi Projection TV, model noted above, cannot properly focus the color. There is too much red and images on the TV appear to be 'ghostly' Tried using magic focus tp adjust color/contrast but problem persists. Any help will be greatly appreciated.

I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.
You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.
I'm no expert, but I think that you have a problem with the convergence
of the 3 color guns. I've been working on a similar problem. As a first
step, have you tried "Magic Focus?" The Magic Focus button for the
Hitachi 53UDX10B is at the left of the small front panel controls that
also include your RCA composite and SVideo connectors. Let the set warm
up for about 20 minutes (as recommended by the user guide), and then
press the Magic Focus button. When you press the Magic focus button,
the set will auto align the 3 color guns. If this doesn't fix your
problem, unplug the TV for at least 4 hours and try again.
