I got an error message that receiver has not recieved guide data from satellite for the last 10 hours. I checked my signals and found I am getting 0 on all even numbered transponders on 99 & 101, 103 is fine. Also, the signal under SWM is 0 for the first 6 and 95 on 7,8 & 9, I have 9 tuners. Is this a bad SWiM or a bad LNB? I just had this installed in September. Thanks for you help.
