I recieved a somewhat older 46 inch projection hitachi the guy said it didnt work I got that fixed he said the convergiance was off so he tried messing with the geometry screws nightmare to get fixed but with hours of sitting there with a test pattern I finally got it and found a couple of cold solder joints on the con board.everything seems great but, the black areas look greenish the color seems fine etc... just the greenish tint in the mainly the black areas. He said the CRTs were replaced last year my question is there a way to turn the amount of green down a little or do you have another suggestion.
