I'm an artist that uses technology quite frequently in my work, mostly TV's, camera's and such, and let me state that I have a very basic knowledge of electronics. I recently made a video projector from an old overhead projector and the screen from an old LCD TV I had from a sculpture. When I dismantled the TV, I removed the light source with the hope of using it in another project. However I have been unsuccessful in getting it to work. The light source was attached to the circuit board by a red and a white wire coming from the light, next to their connection on the circuit board was a ground wire. Now the power range is DC 9-12V, I have the proper AC DC adaptor but it a two prong and thus no ground, how can I replicate the original connection to get the light to work.
