Hello all, I am at a loss and so is DTV technical support... My brother in law called a few days ago and talked them into sending him a free HR20 to replace his HR10-250. It arrived today and I take it out of the box and it is a refurb unit. HR20-700 btw. He already had the Slimline dish installed a while back....Where he has his receiver there is only a Single Line (No SWM). Hooked it up and it already had the latest national release. Went through guided setup and he went to activate it and there is a problem.... According to their records, that receiver is already activated on someone elses account. After about 30 minutes and reading the Serial # and Access Card # 100 times or so it gets activated. Now here is the fun part..... Again only one line...I had it is SAT 1 (FTM) in with a BBC hooked to it.... No locals yet, had to call them back and got them going.... Went to Smithsonian HD channel and it came in and looked very very good... Went to another channel and I get Searching for Signal (771) Tuner 2 on every single channel now. Reboot and all is well.....Most not all of the new HD channels come in fine...But some like FoodHD and HGTV HD I get the searching for signal again and then none of the channels work. Reboot is only thing that helps....Switched from Tuner 1 to Tuner 2 with cable...Switched BBC's...Same thing. Channel 77 and MHD is grey channel and then Searching for Sat signal. One thing that is weird is I can go into Signal meters and I get 100% aquired on Tuner #1 and I get 96-99 on most all transponders on all the Sats until I get to 103(b). I then get 0 on all transponders from 103b...I then can go look at the other sats and 0 on them as well now. Go back to Smithsonian HD (which i was watching for 30 mintues before testing transponders)...Now nothing except searching for Sat signal... Tech support had me reformat and do a bunch of stuff still no joy. She thinks the receiver is bad and I did at first but now I am not so sure. Is there something that can cause the LNB to hang or go bad or whatever it is doing? Again, Most of the new HD will come in great. But then you go to like MHD and then everything is out. Anything else to try? No other lines in house to try it on and I was so pissed after spending a few hours with it that I didnt want to bring it to my house and try it The workaround is that I took off BBC and rebooted and now he gets all of the non-103b signals just fine...All the 70's and such. I would lean towards something wrong with the 103 LNB but why would I get some of the channels and then nothing? unless all the channels I am getting is on the odd or even polarity and the others are not and it is messing something up. Sorry so long, but I am open to anything right now!
