I just bought a used UN32EH4003F and have been unsuccessful in hooking it up to my Direct TV connection. Any suggestions?

Did you connect the Direct TV receiver to the TV with HDMI? Have you selected the correct input? Try a different input. Connect a DVD to make sure that the input works.
Can you get the menu of the DTV receiver on the screen but no channels?
Maybe the lead from the dish is connected to the wrong jack on the receiver.
