Hr34 and H24 installed approx 4 months ago. Performance upto this point has been ok. not as good as my old Dish 722. Today, I received an error stating "Problem communicating with dish. Press select on more info (775)" More info basically states to check connections and power. I also reset the HR34 with no success. Called Directv, the tech walked me through checking the power inserter. He had me disconnect the two coax and touch the copper ends, then reconnect. he the had me unplug power inserter for 30 seconds, plug back in, then reset box. No success. he then said they would have to send a tech, hopefully on Monday, likely Wednesday. called local Directv dealer and he sold me power inserter. brought home and swapped. reset hr34, no success. followed steps above, still no success. called directv, after 20 min hold, was bluntly told I would have to wait for tech. any ideas? was looking forward to olympic basketball.
