I have had a TV set for over 30 years, which is not a flat-screen model. It has finally given out and I am faced with the task of getting a new one. I’m a little bewildered as I’m not really that knowledgeable about technology. Do I need a smart TV or will my provider do that bit for me? If you have any recommendations for a model I could buy, one that’s not too big, I’d also be grateful.
