Not seeing odd or even channels

There are two possibilities that may cause this problem:

• The polorotor inside of the nose cone is not working (Usually a little blue box inside cone). The polorotor is the mechanism that makes your channels go from odd channels (1,3,5,...) to even channels (2,4,6,...) by rotating 90 degrees everytime you change the channel. So if your a channel flicker you can understand that it is doing guite a bit of mileage. A polorotor can typically last between 2 to 5 years depending on the amount of usage of your satellite system. You will have to replace this polorotor (blue box). We strongly recommend that you get an LNBF which does the same job as what is currently in your nose cone but with out this polorotor. An LNBF does both the channel changing and signal amplification at the same time.
• The second thing is very rare (I only seen it happen once). The probe inside of the feed horn (tube part of nose cone) is broken. Hence even if the polorotor is working fine it is still not turning the probe 90 degrees (This is the process that changes the channels from odd to even). What caused this is severe rust or corrosion inside the feed horn making the probe very difficult to turn. You will have to change the feedhorn. Again upgrading to an LNBF would elliminate this problem.
