A:Answeri'm pretty sure that every time you scan, it re scans all channels. but that shouldn't matter. if your new antenna doesn't pick up all your channels, just hook up the first antenna and scan again. it should pick up the channels you originally had and you'll get them all back.
A:AnswerNo, it i not a "Smart" TV. In order to access Netflix you will have to connect another device (Roku, Chromecast, Apple TV, Bluray player w/ Netflix app, etc.).
A:AnswerThis TV is light enough and has rear screw mounts to attach to an under-cabinet TV mount or the wall but you still need to hook it to a signal source; such as a HDMI DVD player and/or cable-TV or TV-dish and/or an antenna. It has a good tuner and got several SW Ohio local stations from a 24" wing antenna in the house. You'll also need an electric wall plug within about ten feet.
A:AnswerI did take it apart as I had to return the first one I purchased. I don't recall having any issue taking the base off. I may have pressed in on the clips, but it released with no problems.
