Good 12v dc TV

I bought one a couple of yrs ago but can't tell you the brand, memory lapse. I went to an appliance store that had a sale on 2 19" models, choice $99. I looked them over. I asked the salesman if either ran on 12v, he had no idea. I looked to see if they had wall warts. One did then I checked the output voltage, 12v and bought it. It's still working but in truth it's in the bedroom and doesn't get used much.
