Too much white.

[Combwork]

Is there any way to reduce the too bright white on a Panasonic "Quintrix" wide screen CRT TV? Reducing brightness in the user adjustments gives a washed out picture, and the white bits are still too bright. White shirts have no folds or creases, they are just bright white. We've tried

From what I've read, getting into the service settings and increasing the blue and green drive might help but I need advice on this. As always, if I screw anything up it's nobodies fault but mine............. The TV was free from another convert to Plasma.
