Hi guys, I bought new

This is a really difficult problem to answer correctly on the first try but here we go. Some tvs will not recognize the introduction of a new component without unplugging the tv for about 30 seconds with the component connected and powering the tv back on. The issue I believe Dish was trying to convey was to make sure the port you plug the receiver into is turned on in the tv menu. Since the dvd works in any of them this seems to be the case. I f you have further difficulties you should contact the tv manufacturer for assistance as they are more familiar with teaching the tv to communicate with the receiver than Dish personell will be in most cases.
