D8000 - HDMI Calibration Failure

[nirvana]

Hi Guys.....again,

I have another problem.....in advanced menu I accidentally clicked the "HDMI Calibration" (which until then, showed "Success"). After waiting a while the TV turned off. I turned it on, but I immediately realized that had changed the settings of color, sharpness, brightness, etc .... I went back into the advanced menu, and I realized that "HDMI Calibration" showed "Failure". I tried several times to get it back on "Success" but in vain. Now it seems that when the TV is turned off, loses image settings.

What do you recommend?? I do a "factory reset"?

Thank you
