Hello, good friends of me I repair I just bought a 32-brand TV

reference 32D2200 brings back your 2 respective coaxial inputs the first antenna and the second one says cable, in the first I place my air antenna for the digital signal and in the second I place the coaxial cable that the cable operator left me installed which I think is analogous and in The menu looked for settings for automatic tuning.
then there is where I have the problem because it asks me for a series of options and in some I correctly tune the digital channels that are 8 channels in an excellent way and cannot find those of the cable, then I change the configuration and I get those of the cable that are 80 channels of excellent form and those of the tdt do not leave anywhere please how do I scan and save the two types of signal. because the old television that I had a challenger brand was 19 inches gave it automatic tuning and that was all the same I found these channels .. at this moment it shows the 80 channels with the configuration that is in the photo that I uploaded.
I thank you for helping me with this problem.
