Question about NetTV DTV34XF3 34" TV
This tv was used in a movie theater where I work. It showed showtimes of the movies and lasted for about nine months. I would have to say that it was on for those nine months with only a few power downs. We used the rs-232 port for the video from a dell computer using powerpoint. One day we were doing some cleaning and without turning off the computer or the tv the cable was unplugged and the picture on the tv flashed off. When the cable was put back on like normal the tv showed nothing. We tried to power off the tv and power it back on, only this time there was a hissing noise in the tv. The power led comes on green when the tv should be on and stays yellow when it is off. after taking the back off the tv the hissing could not be pinpointed. There are no visble fuses that have blown. the tv shows no menus or anyother sort of picture when you change video inputs. Thank you for you time please help. Pyrodizzle
Well what sounds like happened is you blew up the tube in it. have you unplugged it from the wall and just let it sit some times that helps because what will happen is there will be a Electrical build up and it won't work right. an other thing you might want to do is hit the Degauss button on the remote. plug some sort of video signal into it and go through the inputs to see if that helps, mine did that every thing would just be black but i plug in my video camera it would detect it and make sure that the audio cables are plugged in these TV might just be that old that they have to have both audio and video in order to work.
