Hi everyone . I recently bought this tv KDL-40WD655 and discovered strange behaviour of half HD mpeg sources in tv tuner. In digital 576i image is strange mostly broadcasting of my cable operator , especially human faces - they are kinda hardware blurry and not natural tone greeny yellowish. I turned out all noise reduction through main menues , but didn't help . Full HD signal is fine, but SD 576i are with squares in dark and shaky strage must be opposite of processor load . Is there any chance to set this better may be through factory menu ? Also I want to tune audio sync issues - image is delayed from sound in optical spdif out ? Please tell me some factory setting to tune this out.
