Our current TV, a 1982 Zenith 25" console, model number SY2585P2 made in December of 1982 seems to have a glitch. For a few brief seconds to a minute, the screen gets a reddish tint to it and although I still see the picture I also see faint red lines. We turned it off and on once, it went away but there are times it does that for a few seconds. Any ideas what could be causing this? I love this set, it has a special place in my heart, been watching it since we got it in February 1983.
I have attached a pic of it, you'll see one of my cats, "Whitey," as she watches a wreck in a NASCAR race, she loves NASCAR.

On the right side of the pic, you'll see her mother.
