I have an 811 and a 721 hooked to my Mits 65813. I am having a problem with a greenish tint to some of my channels. It is most notable when I am using my 721 and watching NYPD Blue on TNT, I have also noticed it on other channels but not as much as TNT. I would appreciate if fellow members could tell me if they have the same problem while tuned to TNT or any other channel. I also see the same problem when using the 811 but not nearly as bad as the 721. I have done the 64-Pt. Convergence Adjustment and everything seems fine, but yet when I go back to viewing I still get the greenish tint. HELP ?
