If you are sure that your TV, set-top box or cable TV box work fine, but you still can't find channels, replacing the antenna cable is what you need to do, in order to resolve this problem.
If you have tried everything else to resolve this issue, but unsuccessfully, consider buying a new TV. Alternatively, you can buy a set-top box and use it to pick up TV channels.
If there is nothing wrong with channel reception and the signal is strong, but you still can't find channels, take your TV to a repair shop as it might be a hardware-related issue with it, specifically with the TV tuner.
