Facing TV Problems? Ask a TV Technician.
Thank you. To answer your first 3 questions:
1. Model is Dish 301
3. Our satellite receiver does not have these options. What we do have hooked up is the yellow, red, and white cables to the connections on the Samsung TV that match yellow, red, and white. Plus the antenna connection from the Dish receiver to the TV antenna port.
We have not yet tried your recommendation of pressing the SOURCE button on the Samsung to recycle a couple of times, we will try that now and get back to you.
