I had my HR20 and 5LNB sat working fine for years. Equipment or wiring hasn't been touched in 3 to 5 yrs. All working perfectly. This morning I woke up and a lot of my HD channels are out. SD channels work fine. Rebooted... same situation. Checked signal strength. 101, 110 and 119 transponders are all 85 - 100. 99 and 103 are in the 20's. Thats where the HD channels come from right? Sounds like the dish just needs to be aligned? Doesn't sound like a hardware / multi-switch / wiring issue if its just the HD channels and I'm getting a weak signal on them? We had a solid weeks worth of rain about 3 weeks ago, so its kind of weird it stops working 3 weeks later.
