A:AnswerHmmm. Where did you get the replacement power cable from? I would be cautious about what cable I would plug in, as the wrong one could cause electric issues and damage the TV.
A:AnswerYes. it has a RF input for antenna. It also has a digital turner. It most likely will not pick up any analog channels.
Only digital channels, which are the majority of broadcast channels.
A:AnswerWhatever number is listed, divide it in half. This is the true "effective" refresh rate. For example, this product lists a refresh rate of 240hz. This equates to a true refresh rate of 120hz, which is the best you can get. Everything else is fluff.
A:AnswerIt comes pre-installed with Netflix, DirecTV, Hulu, Amazon Prime, YouTube, HBO Now, Spotify, ESPN, Fandango Now, the major networks and a bunch of other apps I don't personally use. There's also a huge list of other video/music/sports/TV apps at your fingertips that aren't pre-installed but can be downloaded. We've had the TV about 3 weeks and we are really happy with the picture quality, functionality, ease of switching between satellite and apps, etc.
