White is more purple than white on projection tv
Hey guys,
I have a 50" Hitachi projection TV and the white on it isnt so white anymore its got more of a purple tint to it. This small picture ( http://home.comcast.net/~raventy/sample.JPG ) can kinda give you an idea. Is there any way to fix that? Thanks! |

The lack of green to the image needs troubleshot and repaired.
There are too many possibilities for the loss of the green without some troubleshooting information. It would be worth it if the set is not one of the earliest RPTV units to have a technician look at it and make internal measurements to provide you with an estimate for repair. |

Early RPTV, anything made before about 1992 (depends on manufacture and
brand). At that age the color problem could very well be simply worn out picture tubes which makes the set not worth repair. A proper diagnosis would still be required to confirm, but were it someone I know with an RPTV that old that looked like that and had gradually gone purple over some time, I would recommend replacement.

Looks like you're missing green, it could be as simple as a cracked solder joint or as extensive as a cracked green CRT, best you can do without calling a tech is to take a peak inside and see if there's any glow at all from the green tube, and if there's not, if there's any fluid leakage, particularly pooled down inside the neck of the tube. |
