About the problem that Chongqing Skyworth digital TV cannot be watched! (SKYWORTH) Urgent!!

Nowadays, when converting cable TV, you need a set-top box to watch it. You need to be in AV mode to watch it. Try it first. If not, it must be either deactivated or no charge. Let me ask first, what is your apartment? If it doesn't work, just put the set-top box and the card. The card should be fine. Go to the radio and television business hall and ask him to help you read whether it is deactivated or not paid! I hope you see TV soon, haha!
