New to Dish TV. Have two receivers, a VIP-222 hooked to port 1 (77) which works fine. The other receiver, a VIP-211k is hooked to port 2 (72.7). If I let the receivers off all day and start the 211k in the evening all channels associated to sat 72.7 will get a 004 error but other channels will be fine, but the 222 hooked to the 77 port will have no problems at all. The signal strength when I go to point dish looks good. Checked and re-terminated cabling and it worked for about 2 weeks. I just changed the LNB set up to port 1 and 3 to see if this helps. Any ideas?
