I had my RPTV calibrated by Greg last year. I'm still very unhappy with the picture quality using a satellite feed. The picture is dark overall. Very difficult to see in regular room lighting (regular viewing vs. cinema time). Darker tones are all blended together as a black splotch. I see the contrast control has been locked out. I assume part of the procedure of the calibration was to make that fixed while leaving the brightness adjustable. But I think I need control of the contrast again. I *hate* this TV. Should've stuck to a tube set. It's a Toshiba 50H82. Thanks.
