I used to have a 23" Zenith TV with manual tuning from 1984 without the Color Sentry feature. I threw it away. I should have kept it.

I'm trying to figure out how old it is. Like I said I don't know the chassis number, which would help indicate the model year. I'm thinking 1978-1983 is a pretty good estimate.
