That's a great suggestion by Jea48. Like hunting down a problem with your audio system or trouble shooting a computer, go through a process of elimination.
By hooking each of the two receivers that are having reception problems in place of the HDTV unit that is working fine you'll be able to see if you just have a bad connection or if the problem lies with a malfunctioning or improperly set up receiver.
Good luck!
