After a lightning storm I am unable to receive some channels on my directv system. Some channels come in fine and others that I once received now say searching for signal. I checked my signal strength and it is 98, but only on the odd numbered transponders. The even numbered transponders are zero. I have a single LNB with two receivers in different rooms on different surge protectors, both receivers are responding the same way. I disconnected the power on the receivers for 30 minutes and reconnected them, but the problem still exists. On Directv I can receive channel 490 but channel 491 says searching for signal. Any help would be appreciated.
