How to Improve Remote Control Effectiveness

This article tells you how to increase range and sensitivity between remotes and TVs, Set-top-boxes, etc.


  1. 1
    Locate the Infrared receiver on your TV set or device. An IF receiver (RX) is an optical sensor that detects infrared light signal from the IR transmitter (TX) on your remote controller.
    • Look for the receiver on the front face of the TV or device. Most often, the IR receiver is discretely placed along the top or bottom edge of the screen and covered by a red or gray film or plastic lens.
    • Use a flashlight to better locate the receiver lenses. Sometimes they are so small and placed within the protective edge of LCD screens or the covers color match and are flushed in with the surface.
  2. 2
    Inspect your remote controller for vent or damaged infrared light bulb. A damaged or scratched transmitter diode may not effectively send out signals to your device.
    • Remove any buildup grime or dirt from old remote controls.
  3. 3
    Polish scratched or dull Infrared diode lenses on old beat up remotes.
  4. 4
    Keep the IR/RX surface lenses clean and dust free. A dirty IR can diminish effective controller distance by several feet.
  5. 5
    Move the TV unit closer to the edge or elevate it If the receiver is located at the bottom of the screen. Having the unit too far back from the edge may obstruct the line of sight between the remote controller and the receiver.
  6. 6
    Many devices like STBs have a dark cover over the sensor and/or sender for the remote control signal. Remove it or sometimes it has a thin film of color that can be peeled off the back.
  7. 7
    Try putting an aluminum foil reflector and/or collector around the sender/sensor.
  8. 8
    Replace remote batteries with a fresh set every 3 - 4 months.
  9. 9
    Never mix different batteries or new with used. Alkaline batteries may be too strong for a remote control even though they are rated with same voltage.
  10. 10
    Remove the batteries if a remote control won't be used or stored for longer than a month.
  11. 11
    Always point remote controller directly to the receiver.


  • Be careful not to short electronics with foil


  • Stick a note with programming codes within the battery compartment/lid for easy reference when replacing batteries.
