Do a search for Seiki and you will find this has been thoroughly discussed. It's not an analog TV, but as I understand, it lacks a QAM tuner, which decodes the cable signal.
Our experience with those cheapo Seiki TVs has been that some campground cable systems work, and some don't. Many have just replaced them, we may do that some day, but until then, we just pull out a DVD or a book to read.
Only some of us learn by other people's mistakes, the rest have to be the other people!
