SONY RMF-TX300U Smart TV Remote Control

Genuine OEM-Grade Replacement for Sony

Make your Sony TV fully usable again with the RMF-TX300U. Pre-programmed, factory-matched, and ready out of the box.

Standout Details

• Battery-Friendly: Engineered for low standby draw — a pair of AAA batteries typically lasts a full year of normal household use.
• Input-Switching Done Right: HDMI, AV, component, and tuner cycling work via the dedicated source keys, not a buried onscreen menu.
• Hand-Checked: Each remote is power-cycled and key-tested before it goes into a shipping box.
• Tactile Feedback: Soft dome contacts give the same press-feel as the factory remote — both short taps and long-presses register properly.
