Learning about an old TV

 I would have never thought that paper is the material of choice for containing small glass tubes in place behind a traditional LCD television. After this screen went out at the NRL operations office, the superintendent mentioned I could look into the potential repairs of the screen. I took it into the special projects shop and began to poke around inside the electronics with my friend Dane. We were able to figure out a particular test point voltage (well, a labeled connector voltage) was not correct to activate the backlight inverter.
