Hi Sue, I have a JVC 19in (LT-19 something or other) bought from Comet about 5 months ago, can't remember the exact model number and I'm not on the boat at present to check it. I bought a 12v/12v stabilised supply from maplins for about £30 which plugs into a 12 volt 3 pin socket on the boat and then into the 12 volt socket on the rear of the TV. It works very well, is a really good picture and seems to pull in a good signal in areas where the previous TV would not. The only slight negative is that the sound quality is just a bit tinny but very pleased with the TV in general and no regrets about buying it. Only time will tell how reliable it is. Hope that helps --- tosher.
