I read an article about AGC that the agc is for antenna connections but it’s somewhat not needed for a cable or any other video source so I don’t know if the agc is not working will it still knock out the video and sound from another source such as vcr cable line dvd.

It absolutely will take out RF from a VCR or DVD player I've seen it happen on my own sets more than once.

The amp bias is controlled by the AGC circuit. If AGC is defective you can get absolutely no reception like the IF tubes are removed all the way to problems like signal overload and red plating IF tubes.
