I usually don't take a TV that is considered to be in "junk" status today, but this 1991 KTV 19TEC1 19" mono TV with no video input

that has been sitting in my closet for more than four years was once owned by a rockstar singer in Trapt band. (
http://www.trapt.com) and (
http://en.wikipedia.org/wiki/Trapt). He got it new from his parents when he was 10 years old, probably as a birthday gift, and used it for 12 years. It was then handed down to his brother in 2003 to use for his college dorm room, which I also lived on the same floor, and he was a friend and a huge fan of me one time. At the end of school year, he gave it to me along with the desk chair because he could not put them all into his car when he moved out.
So, I have this KTV 19TEC1 here and don't know too much about it. It was last working four years ago when I last tested, and it hasn't been used since. I do know that KTV stands for Korea Television, and it was the fourth largest Korean television manufacturer after Samsung, GoldStar, and Daewoo. Unfortunately, KTV didn't stay in business for long.
I like to know some positive things about this KTV 19TEC1. Have you ever seen one? Who made the picture tube and how reliable was KTV? The lead singer in Trapt, at that time he was attending University of California at Santa Barbara in the late 90s, probably did a lot of cool shit to this TV, like all of his bandmates came over and watched porn videos for many hours and got drunk, as well as PlayStation games. The set received moderate-heavy use. If this TV wasn't owned by a rockstar, sadly, it would be in the trash can already. Thanks to anyone who can give me more info about KTV TVs.
