If your TV isn't connecting to any of your devices, here are some steps you can try to resolve the issue:
Check Connectivity Settings: Make sure both your TV and the device you're trying to connect are on the same Wi-Fi network. Sometimes, devices won’t show up if they're not connected to the same network.
Restart Devices: Restart both your TV and the device you are trying to connect (like a smartphone or tablet). This can resolve temporary glitches.
Update Firmware: Ensure your TV’s firmware is up to date. Check the manufacturer’s website or the settings menu for any available updates.
Reset Connection: If you’re using a feature like Bluetooth or screen mirroring, turn it off and then back on again on both devices. Sometimes resetting the connection settings helps.
Use a Different Method: If screen mirroring or casting isn't working, try connecting via an HDMI cable or a different method to see if the TV responds to any input.
Factory Reset: As a last resort, you can perform a factory reset on your TV, but remember this will erase all settings and customizations, so use it only if necessary.
If the problem persists, consult the user manual or contact the manufacturer’s support for specific troubleshooting guidance.
