It might. Have you checked the actual LNB to see if maybe there is a crack that has allowed water to get inside and is actually affecting the LNB.DarkAudit said:My HR20-700 has been susceptible to the rain fade issue knocking out tuner 1, but now it will lose tuner 1 even in clear weather.
Test run during the fail period has tuner 1 and LNB output failed.
Resetting the receiver brings back tuner 1. Signal strength in the 80s and 90s on both tuners.
Per the DirecTV tech support, I swapped cables. Tuner 1 still fails. Tuner 2 signal still in the 80s and 90s.
DirecTV is sending me a new HR20-700 (at least that's what the CSR said. The email just says an HD DVR). after reading a few of the other threads, is this going to make a difference?
