Hi jsvycit,

I'll be happy to answer this.

1. I haven't heard of the symptom you're presenting, but you can try resetting Smart Hub: http://support-us.samsung.com/cyber/popup/iframe/pop_troubleshooting_fr.jsp?idx=382162&modelname=UN60ES8000F&modelcode=UN60ES8000FXZA

And if that doesn't work, you can try a factory settings reset: http://www.samsung.com/us/support/SupportOwnersFAQPopup.do?faq_id=FAQ00046660&fm_seq=49625

2. If they did the professional calibration like you said through the service menu, you should be fine.
