Have an RCA DTS dolbey digital with built in DVD player has three jacks in front of TV and jacks on back of TV. I hooked up Sony DTS dolbey digital DVD player to TV and I only get sound but no picture. Have red yellow and white plug ins. How do I get a picture on my TV?
Either it's not hooked up properly, the cable is bad or the port is bad. Test the DVD player with another TV to make sure the cable and DVD player are working.
