We purchased a 60" Samsung LED. We are not able to get it working with our Dish network receiver. We receive audio from the satellite but the screen is pink with black vertical lines. The original TV was set to channel 21 and the receiver was plugged into the component video ports. The new TV uses a component video converter. We plugged the receiver component video cables into the component video converter supplied with the TV and the results are that we hear audio but the screen is pink with black vertical lines. We plugged the DVD player into the same conponent video converter and we are able to watch a DVD so we know it is not a cable or port issue. Any suggestions?
