A:AnswerIt has a Coaxial cable input, along with HDMI inputs. When I started the TV for the first time, it asked me if it would be attached to a Cable Box. So, Yes, it should take a cable box without any issues.
A:AnswerThis sounds like you have a faulty power board and it is not regulating the power correctly. Unplugging it is a cold restart and will temporarily fix the issue but it will eventually stop powering on at all. If it is under warranty, you should file a claim. If not, you can buy a new power board and replace it if you are tech savvy.
Otherwise it's time to buy a new one.
