Using a set-top box to encounter a black screen

The first time I used a set-top box, the HDMI cable was plugged into the TV, connected to the power supply, and the black screen of the TV was encountered. The reason was that the TV remote control selected the signal source to switch to HDMI, and then it could enter the TV screen.
