What effect does a bad connection at the splitter's input port have on TV sets?

The correct understanding is that a bad connection at the splitter's input port can lead to signal degradation or loss for all devices connected to the splitter, including those at the output ports. Since the input port is responsible for distributing the incoming signal to the various connected outputs, any disruption or interference at this initial point will impact the quality and strength of the signal being processed by the splitter.

This means that if the input is compromised, all signal pathways branching out to the output ports suffer from the same degradation, consequently affecting every TV set connected downstream. Therefore, it is crucial to ensure that the connection at the input port is secure and in good condition to maintain optimal performance across all connected devices.
