I've got a situation that I'm having trouble understanding, and wanted to run it by the experts here to see if you can help me out! Setup: Slimline-3 dish with SWM LNB, 3 HD DVRs Installed in October 2009, and been running smoothly ever since...until the past couple months. In April, I was getting bad pixelation on many stations, and the signal meter was showing most transponders in the 50-60 range. I finally requested a dish realignment, and that fixed up my pixelation issues, and the signal meters have jumped up to the 90s for all active transponders on my receivers. The SWM signal strength is typically showing as 98-99. In May, my HR22 started having issues showing picture at all (black screen), and I was getting tuner 2 failures in the system test. It was also taking a really long time to boot out of the blue screens (5+ minutes). The tech came out, and determined the receiver was bad (it couldn't download new software?) and swapped it out for an HR24 that so far has been working just fine. In June, another one of my receivers (HR21) had twice over three days gotten into a state where the picture was just black, but the receiver (DTV) UI worked (similar to what happened to my HR22, but I wasn't getting any tuner error messages). No searching for satellite messages or anything like that. When I tried to run the receiver self test, it basically hung at 9%. After rebooting--which took an extraordinary amount of time, maybe 10+ minutes--everything eventually was back to normal and the system test reported no errors. I requested a service call, and when the technician came and diagnosed the problem--to make a long story short--he said there's too much loss on the line and that all of the cabling inside the house would need to be replaced. Now, this is despite the fact that I'm still seeing all transponders in the 90s in the signal meter, and SWM in the 98-99 range. Some more details here...the tech hooked his meter up at a few different points in my setup, and when he ran some tests it came back with all 'X's in the boxes instead of checkmarks (I don't know exactly which test this is on his meter), meaning there was too much loss on the line. He determined the signal strength to be the following: At the ground block (right off the dish): -26dbm At the comm closet, where the line comes in and prior to being split to the receivers (4-way splitter): -32dbm At the wall plate where the receivers are (we tested two and they were both the same): -47dbm The house was built in 2006 and I believe the wiring is RG6 copper clad steel, but I have to confirm. The numbers above are what was on his meter, but honestly I'm not certain what measurement they were for. The comm closet is located on the 3rd floor, and from there the lines run straight to where the receivers are located. So...here are the questions I'd like to understand: Are the signal numbers reported by the tech normal/reasonable or are they out of line? If indeed I do have so much signal loss, how come my receivers seem content to register in the high 90s for satellite and SWM strength in their UI? Are the issues I've experienced with my receivers common, and is there some other cause (software/bad hw?) that might explain it? I find it odd that my system has been working near perfectly for 2.5 years even with a poorly aligned dish, and now all of a sudden my home wiring is bad and needs to be replaced. Am I just lucky and on the bubble of acceptable signal strength? Or is there more to it? Thanks for reading this far! Hopefully I've included all the details you need but if not, please let me know.
