If you're wondering if TVs are secure, they are! Just don't connect them to the internet! It sounds simple, but the temptation can be real for those who want to use apps to go online. If you keep the television offline, it can't secretly watch you (assuming the company behind it is shady). Get an Apple TV or Roku device, which are kept up to date. If your TV gets infected, the issue can even bleed into your network...which would be a huge problem.
