We just had a new sl3 dish installed to replace an old sidecar dish and a new HR34 also installed. Shortly after installation the HR34 periodically has the searching for signal come up or the picture freezes for 1/2 second. It does not happen on my other 4 HR20-21. System details: 1 new hr34 4 existing hr20-22, one moved to a new location. Directv installed swm16 replacing my self installed swm8. Hr34 on one leg of the swm alone. The line needed to be extended. The installer added length connecting with a ground block.Others on the other leg. Three runs off the swm split with a green label spitter (previously installed) 2 hr 20 share one of the runs split with a power passing splitter. 2 other direct from splitter to box. Any ideas?
