The Fire Edition HDTV that is made by Toshiba is a great UHDTV for the price for the features that you get. The main feature of this HDTV is the Alexa voice recognition and assistant. Aside from that the 4K resolution and HDR are also great for this HDTV. This maybe the great bang for the buck HDTV for this year (2018) and I would definitely recommend this to everyone who are new or upgrading for a 4K HDTV.

  1. I bought a Fire Toshiba yesterday. I have FIOS fiber optics cable. I had a hugh lineup of channels on my FIOS line up. Generally you can switch all your lineup to a new TV by running channel search. I can't seem to be able to do that on my NEW FIRE TOSHIBA. Thus, I have to download each and every channel I want or had. Anybody know how to get my original FIOS lineup?
