What to do if IR sensor is not working?
Andrew Campbell What to do if IR sensor is not working?
Troubleshooting Techniques Try power cycling the TV, too, by uplugging it and letting it rest for 15 minutes before plugging it back in. Don’t rule out the remote, because it may simply need a new pair of batteries. Or, the remote may not be sending an IR signal to the sensor.
What can interfere with IR signals?
You can get IR interference/jamming from nearby sources like compact fluorescent lights, LCD/Plasmas displays, etc. 3. Check to see that the problem truly lies with the IR signal. Check your remote’s batteries and the connections on the cables to your speakers, receiver and television, among other components.
Can my phone send an IR signal?
Some Android devices have a built-in IR transceiver. This means that they can send and receive IR signals (the same thing used by your typical TV remote control). This makes it possible to control TVs, steros, and other equipment with Unified Remote.
Can a sound bar block the IR signal?
Placing the sound bar too close to the TV may block the IR signal. In that case, moving the sound bar is recommended. IMPORTANT: Make sure that the remote control of the TV cannot control the TV before enabling the IR repeater function of the sound bar.
How are IR signals sent to the sensor?
But before we do that let’s first examine exactly how data is being sent from the IR remote (in your hand) to the IR receiving sensor (on the breadboard) For this example we will use the Sony power on/off IR code from a Sony TV remote. Its very simple and commonly documented!
How does the IR receiver in your TV pick out signals?
When you use your TV remote, an IR LED is used to transmit information to your TV. So, how does the IR receiver in your TV pick out signals from your remote among all of the ambient IR? The answer is that the IR signal is modulated. Modulating a signal is like assigning a pattern to your data, so that the receiver knows to listen.
Why does my sound bar stop working on my TV?
The sound bar is blocking the IR sensor of the TV. The remote control of the TV may stop working if the sound bar is placed in front of the TV. Placing the sound bar too close to the TV may block the IR signal. In that case, moving the sound bar is recommended.

How to troubleshoot an IR sensor on a TV?
Follow the steps below to troubleshoot this issue: 1 Make sure the remote control is set properly to control the TV. 2 Make sure there is nothing in front of the infrared (IR) sensor on the TV that may be blocking the signal from the remote control. 3 Make sure you are pointing the remote control towards the IR sensor.

Can a Sony remote listen to an IR signal?
Lets pretend we have a Sony remote, and we can look at exactly what light is being blasted out of the IR LED. We’ll hookup a basic light sensor (like a basic photocell!) and listen in. We won’t use a decoder like a PNA4602 (just yet) because we want to see the undecoded signal.
