When I go to scan the channels I can not get system to lock on to sat 119 and 129 to scan. It will scan 110 without any trouble. Was scanning all three sats and working good before but went down and when I tried to rescan couldn't get 119 and 129 to scan at all. I have D--H/N----k system on another tv that uses same dish and getting signals from all three sats on it.
