The primary reason a TV stops responding is often external to the sensor board itself. Common causes identified by experts from JustAnswer and iFixit include:
: Physical objects (furniture, decorations) or built-up dirt and grime blocking the IR receiver on the TV's lower bezel.
Before assuming the TV's sensor is broken, use these steps to isolate the issue to either the remote or the TV:
: The IR sensor board or the internal cable connecting it to the main motherboard may have failed. 2. Diagnostic Testing
: External light sources such as fluorescent lights, neon signs, or even bright sunlight can "jam" the IR receiver.
