Diagnosing problems and troubleshooting
Despite the simplicity of the technology, users may encounter difficulties. One common issue is that the TV isn't visible in the list of available devices. In this case, ensure both devices are simultaneously in search mode. Sometimes, rebooting the Wi-Fi module helps: turn the wireless network off and on in the settings of both devices.
Another common issue is audio and video desynchronization or intermittent connection drops. This can be caused by signal interference from other devices or a microwave oven. Try clearing the air or changing the Wi-Fi channel in your router settings (if you're using a hybrid connection), although it's more difficult to influence the channel with pure Wi-Fi Direct.
⚠️ Attention: If you receive an error "Unable to connect" or "Incorrect PIN" when connecting, try deleting the TV profile from the list of saved networks on your phone ("Forget network") and starting the pairing process again from the beginning.
If you see a picture but no sound, check your smartphone's audio output settings. Sometimes the system defaults to audio on your phone, even when the video is playing on your TV. Also, make sure your TV isn't set to "Quiet" or "Low Volume."
