A:AnswerThere are 3 HDMI ports although the salesman said there were only 2. a couple of USB ports and the standard RCA plugins. External audio is through a optical port only which was a disappointment. It has the Ultra 4k LED picture which gives a really sharp picture. We did not get the Smart TV, have enough devices that connect to the internet without the TV.
A:AnswerOnly difference between this one and the 6300 is the 6300 comes with a smart remote. I went with this model because it was $100 cheaper and I am completely satisfied
A:AnswerI think what you are doing wrong is, you are pressing the volume button down. You need to press upwards or downwards.
I know this because my girlfriend had this same issue. Press upwards or downwards.
