someone has a sense of adc result model un48ju6700 / 6670 or like to get an idea of how to start the calibration? I put to right and has failed calibration, now ta all wrong. One more thing, every time my television back to stay with strong brightness, have to take the cable and put again to return to normal, how can I solve this little problem that made me lose all the original factory calibration of my ju6700?
