The LNB has two things controlling it..

1# Is the voltage which not only powers the LNB but also switches the LNB polarization (13v for Vertical and 18v for Horizontal) If broken then you only get half the channels.

2# 22Khz tone (used on Universal LNBs). This switches the Internal oscillator from 9.75Ghz (no tone) to 10.6Ghz when the tone is switched on. If the tone is broken or degraded by the cable/connectors then you will not be able to receive channels on higher frequencies (11.7Ghz and above). In your sat menu you should be able to set the LNB for Auto Tone and 9.75Ghz/10.6Ghz
