I’m experiencing random problems with some of my local channels (Los Angeles 5, 9, etc) as they suddenly start showing severe pixilation and signal loss and the 771 searching for signal appears in all my 4 DVRs. This is a very random problem happening once every 3 to 7 days and the way to return to normal is unplugging the PI-28 power inserter for a few seconds and then plug it again. I have a SWM-8 connected to a 1x4 splitter feeding 4 DVRs, the PI-28 power inserter is installed interior and the whole system has been working without problems for many years. When checking the Satellite Signal Strength during failure there is a loss of transponders all over the Satellite 103. Transponders numbers on 103 go from normal to 0 and most of the time during the failure they show 0 signal with intermittent and random jumps on the levels. The system doesn’t show any problem with 103 when checking only the Satellite Signal Meters. Because the failure is random I don’t know where to start to solve this so I’ll appreciate any help from others here that may have already suffered similar failure. Thanks in advance. Ed.
