I have a problem with setting the signal on the TV. Due to renovation, I had to disconnect everything. After connecting, there is no signal at all. I replaced the antenna power supply, but it does nothing. All HDMI cables are well connected.

I have no idea if I have lost any part. I tried to connect through this splitter and for a minute the signal was. I don't know why it was because this cable hangs freely and is not connected to anything. Thank you in advance for your help.
