Preparing equipment and checking the signal
The first step is physically connecting all system components. Image quality directly depends on the condition of the antenna cable and the antenna itself. If you are using an indoor antenna with an active amplifier, make sure it is connected to a power source, if required by the manufacturer's instructions. For a digital signal, DVB-T2 It is critical that there are no strong bends in the cable.
Next, you need to check the operation of the network module. TVs TCL support standards WiFi 802.11ac and higher, which ensures high data transfer speeds for streaming. However, for receiving over-the-air channels, the internet is used only indirectly—for downloading current frequency lists or updating tuner software. Make sure your router broadcasts a signal in the 2.4 GHz or 5 GHz band, depending on which provides better reception for your TV where it's installed.
If the signal is weak, the picture may appear blocky or the audio may lag behind the video. In such cases, using a higher-gain antenna or installing an external signal amplifier can help. It's also worth checking for interference from other household appliances that operate in the radio frequency range.
