A:AnswerWe use a Roku box on our sets and they work great with these TVs. I like having the WiFi in the box for any upgrades. Another we use Firestick on and the stream is great on that to.
A:AnswerYes you can use a Roku with this set. There are HDMI, and the RCA (red, yellow, and white) ports. So which ever model Roku. Even an USB port if that is the one you have.
A:AnswerHi Beto! It depends on the residential voltage of the particular area in Brazil. Sharp TVs sold in the United States are 110V 60Hz only. Also, the warranties are only valid in the USA. If you have any further questions, please contact us at 1-888-935-8880.
A:AnswerThey are on the bottom. If they were in the back like on most sets even on a table you wouldn't have gotten good sound, Since these are on the bottom the sound is great! You won't be disappointed in this set.
