Hello all, I am at wit's end trying to figure this out. Here's what's happening, any info would be very much appreciated! To start let me say this, I have checked all the gimme's (ie. f-conns, cable, power supplies, swapped boxes, etc.). System KA/KU5 65' Solid Copper Perfect Vision Cable DTV6PWRPOL-02 w/ Power Supply 2' Solid Copper Perfect Vision Cable SDMSD606---2' Solid Copper Perfect Vision Cable---SWM16 w/ 29v Power Supply - - - 2' Solid Copper Perfect Vision Cable SWM8 w/ 29v Power Supply 2' Solid Copper Perfect Vision Cable from both SWM8 & SWM16 each going to green label 8 way. I have 6 tuners on each 8 way with the longest run, to all H25s, at 60' I also have a deca attached to each 8 way. So the frustrating part is this...there intermittent 775 error happens at no set times, days, etc. as well as across the entire system. When I get these errors, it can be on 1 receiver, or multiple receivers across different 8 ways. I know that since it happens across the entire system, the cause has to be originate from something they all have in common! Knowing that I have replaced the following. (SWM8, SWM8 Power Supply, SWM16, SWM16 Power Supply, LNB, Polarity Locker, & Vertical Tap). Let me also add this, the 775 usually goes away as soon as I pull the power from the entire system (receivers not included). Any ideas where or what to try next?
