I had a hr20-100 installed on saturday 7/28. Everything went fine and works great until last night. Go to watch dhd and says no signal in sat 2. Checked cabels and swapped sat1 and sat 2 cabels and get same error. 2nd tuner works on all but tnt hd. CHeck sat signals and tuner 1 is in the mid90's to 100. 2nd tuner is much is in 70's-80's, some even lower. Can it be a bad 2nd turner? That is my guess since if I switch cables I get the same error, and same signal strength in sat 1 and sat 2. Would a full power down and reboot help this, or will I need a new hr20? Thanks in advance.
