After signing up some international channels i noticed they were dropping out intermittently. Then i check the system info and noticed that sat 118 has red box with 'x'. Suspecting it's the cause of the problem. It sees 110 and 119 with ~60 signal strength. 118 has nothing. But when i check the switch, it seems ok. (DP34) seeing all 3 (i think since it says Tuner 1 and Tuner 2 and list all 3 sat). I have D500+ dish. Clear line of sight in Pacific NW. Any idea?
