Does anyone at the Pudding Hotel turn on the TV? When I turned on the set-top box and the motor switch, there was no image. ..

Turn on the set-top box and the motor switch, and there is no image. The possible reason is that the TV signal source has not been switched.

1, press the "signal source" key of the TV remote controller;

2. The TV screen will display video 1, video 2, USB, HDMI 1, HDMI 2, VGA, YUV and other options.

3. Select the project by the up and down keys, and determine the options by the left and right keys;

4. For example, if the high-definition set-top box is connected to the TV with a high-definition multimedia interface cable, then the corresponding high-definition multimedia interface ("HDMI 1" or "HDMI 2") should be selected; If the standard set-top box is connected to the TV through audio cable and video cable, switch the signal source of the TV to the corresponding "video 1" or "video 2".
