The set-top box has a preset delay time when switching channels. This differs slightly depending on the service provider that provides the set-top box.
However, it may also take a long time for the screen to change when switching the channels as a result of a set-top box error or communication problem.
In such a case, initializing the set-top box may solve the problem. - If the symptom persists after initializing the set-top box, contact the service provider that you are using.
