    I also have the color issue, my TV color is mostly red and blue, my green is starting to fade out, and the color is getting darker, flesh tones are looking more orange/red than flesh color.
    What do you think it will cost me to get my CRT replaced?

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.

Colors are way off. Too much orange, colors eratic.


You need a convergence kit. Search Goo*le and tvrepairkits.com will have a kit make for your specific tv.

Replace with the kit and your colors will be better than ever!


Thank you!

Blue streak and no red on Hitachi 50V500A rear projection TV


Check a second source such as a dvd player or game system using different cables. If the same issue happens then the tv will need repair. However if the issue is not the same it is either cables or the original source.

57F500A, powered light on with no sound/picture, ticking noise


Over the years of servicing these sets and others for Convergence issues, I have on several times gotten defective Convergence ICs. In your case where a Resistor is now open, (Probably a 1.5 ohm 1/2 watt), I would suspect you had gotten a hold of a defective IC. I would replace them both again. Make sure to use Heat Sink Compound between the ICs and Heat Sink.(Just a thin coating on the metal area) You can get the heat sink compound from Radio Shack. They should also have the Resistor you need.
Good luck,

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.
