A:AnswerThe great thing is that Roku has a Spectrum app. You can use your cable service to stream without the cable box. Save $ not having extra set top boxes.
A:AnswerYes it has HDMI inputs, RCA inputs (red & white audio and yellow video) and a RF antenna input. Roku is free, just sign-up and supply & credit card for file. You can access Netflix and others. Some streaming video is free.
A:AnswerI can only answer with a question. Was this a reconditioned unit? Best Buy will be able to help you reset the tv so you can enter the proper information.
