90% chance that is the fast color changes overloading the bandwidth available on the TV channel, and/or the compression method of transmitting the live signal (believe that is a cause of some of the green you see), and/or the compression of the signal from the cable provider.
If you own a blu-ray of a movie and see the same movie on cable TV, you'll be amazed how much of a difference there really can be (and that is on something created under near-perfect conditions, almost the polar opposite of LivePD). You will likely see compression effects (blockiness) most in highly detailed areas, especially with motion, like looking at lots of leaves/grass or at slightly choppy water. The broadcast has a set, finite amount of bandwidth while the bluray tends to have a much higher bitrate. You might also see less color banding in large expanses of sky on the bluray.
So really, don't think it is likely to be your TV as much as the content being displayed. If you have a computer monitor with an hdmi input that you can try, maybe see if it acts exactly the same. I expect it will.
Unless you are trying to convince the wife you need a new TV, in which case, you absolutely need a new TV. And a new gun to go with it.

The link to the CDC uses a lot of "may" and "might". I agree with may and might. However, at least hundreds of millions of people have been collecting and living off properly collected and stored rainwater for thousands of years.
This law firm wrote a very shoddy letter. Misspelling and bad grammar. Jail house lawyer stuff. Im not surprised the courts didnt take it seeiusly. No case identifiers or citing any laws. Im not surprised this is going nowhere. Ask for a full refund of dues. Get a competent legal firm.
