Like-for-Like Replacement for Sony Smart 4K Ultra LED HDTV

Get your Sony TV back in working order with the RMT-TX300U. Built to factory specifications and ready to use the moment you drop the batteries in — no codes, no pairing, no headaches.

Engineering Highlights

  • Direct-Fire IR: Tuned for the front-bezel sensor on standard TV cabinets — works through tinted glass and dark plastic panels.
  • Battery-Friendly: Engineered for low standby draw — a pair of AAA batteries typically lasts a full year of normal household use.
  • Battery In, Done: Slip in a pair of AAAs, point at your TV, and start using it. That's the whole setup.
