A:AnswerWe use an outside antenna with an amplifier and get more than 80 channels. Some stations have a very bad lip sync problem but most do not have any problem. Therefore, I think the problem is with the specific station.
A:AnswerIt does have RCA output for a sound bar.
I doubt that the TV will control the sound bar volume. I also have a new Samsung 9000 series hooked up to a Samsung Sound bar and the TV vol control does NOT control the sound bar volume. Or at least I cannot figure out how to make it do that. I have a separate small controller for the sound bar.
A:AnswerThis has a NTSC and will not work for over the air reception in India. Any device you connect via HDMI should work so if you have a Satellite box or DVD/BlurRay player those should work. Plus you would need a power converter as this is for a 120 volt and India runs on 230V.
