A few days ago, I had an install at my new house. I brought a HR20 and HR21 with me and had another HDDVR installed, which turned out to be a HR22. I had a SWM install and both my HR20 and HR21 seem to be working without any issues. I am having issues with my HR22 however. I keep getting intermittent 'Searching for Satellite Signal on Tuner 2' errors and sometimes when I change channels, it hangs on a gray screen. I have checked my signal strengths and they are all in the 93-100 range on Tuner 1, Tuner 2, and SWM. The 771 error does not hang around long enough for me to check the signal strengths at that time, but it is certainly annoying and distracting to watching shows. I have already tried unplugging all units including the power inserter, then powering up one unit at a time. That did not work. Any thoughts on this? Something wrong with the SWM or perhaps a bad HR22? Based on the signal strengths, I wouldn't think it would be an alignment problem. I have been a DirecTV customer for years, but a novice when it comes to the SWM. Any advice you all have would be great.
