Dish installed a 622 and now my tv2 doesn't work. I called dish and went thru the motions of setting the remote address and the tv2 to channel 73. A program appears, but it's not in our dish lineup (TVHot..very old tv programs). I try to change the channel at the receiver, but it doesn't change. It's like the remote doesn't work. The remote worked fine before the change. I did change the batteries in the remote. Any ideas of what I need to do to correct this? Thanks.
