I’ve been trying to connect my Sharp LC-19DV24U to my old Sony STRD515 receiver. The receiver has no digital input/output. I bought a digital to analog audio converter and a coaxial cable because the tv only has a coaxial output. I connected it all and no sound! I tried all the different inputs phono/cd...Then I tried connecting the yellow video line from receiver to tv and that worked with DVD player. However once I went back to the other inputs - no sound. I had coaxial audio out from tv go into coaxial audio in of converter. The red and white of converter went to the red and white audio on receiver in the tv/ld line. Lastly as a final effort, I connected the yellow video in to tv/ld video in.
