New SWM Install with No Signal on Tuner 2

I just installed a Slimline 5LNB dish and SWM-8 at my parents house. The 4 outputs of the dish go to the SWM module in the attic with 15 foot RG6 QUAD CCS. The SWM1 output runs about 40 feet to a SWS-4. The power passing leg then goes 30 feet to the PI and then a 1 foot cable from the PI to my HR21-200. The reason for the SWM is only 1 cable to get 2 tuners and the reason for the SWS is my parents plan on getting a new HD TV and receiver and the current cable from the old dish (3LNB still installed for time being) is in the attic above my room so it will be disconnected from the 3LNB and connected to the SWS4 without having to run new coax or use a barrel connector.

I get signals of mid to high 90s or 100s for tuner one sat 101, 110, 119. High 70s and mid 80s for 99 and 103s, mid 80s to low 90s for 99 and 103c. I know 99 and 103 could be peaked a little better but it was getting dark at the end. For the SWM signal level, all 9 transponders show a reading of 94-99. How come no signal is found on tuner 2 and why are all 9 swm transponders lit up (understand only ones used show signal strength)? I have tried RBR as well as unplugging both the PI and HR21 for 15 minutes, then plugging in the PI and waiting 3-4 minutes before plugging in the HR21. I have run the various tests and sat setup again to verify all settings look right (slimline, swm, dual tuners, etc.) but it keeps saying no signal on tuner 2 as well as 771 searching for signal on satellite in 2 messages.

What do I need to do to get tuner 2 to work? I will leave both unplugged all night and retry in the morning pending other answers/suggestions.

Thanks

Thanks

Just an update, fired up the PI, took a shower then plugged in the HR21, still same problem. After work I will wander to radio shack and get a barrel connector and bypass the splitter. Also try running off SWM2 instead of SWM1.

Also of note during install, running one line directly to HR21 with BBC to align and peak dish showed signal on both tuners. Does this seem odd to anyone?

Ok, now i have the PI on SWM1 with 20 ft rg6, no IRD connected. One line from SWM2 to my HR21 with a barrel connector instead of the SWS4. Still no tuner 2. Does this mean my SWM8 is defective? I receive all channels (I have premier) in SD and HD where applicable on tuner 1. What is wrong with my tuner 2? Any other suggestions?

Yes, see second paragraph of original post. Also if it was only set for 1, it wouldnt kep showing the searching for signal message.

I was able to get some picture for a second when using a barrel connector after the last reboot. Checked signal strength and got a couple of 30-40 readings on the 101. Double checked the barrel connector I found laying around and it doesnt have the blue middle so it isnt a high frequency one. Guessing maybe my sws4 is bad. Off to the shack for either a new splitter or 3high freq. barrel connector. Any reason why a bad sws4 would allow 1 tuner but not 2?

Tried with a 40-2150 mhz splitter from RS, no luck, same problem. I will try again with the non high freq. barrel connector and see if I can get those transponders to show again. I hate to ask again, but anyone else have any suggestions on how I can get this working?

Ok, found a high freq barrel connector (from the standard cable coax in the attic). Getting low signals on some transponders on tuner 2. I will post all of my signals and let me know what you guys think of them.

Seems every signal on tuner 2 is less than half of the value for tuner 1. Also notice some of the SWM tuner 2 are 0 instead of half.

What do these signal levels indicate to you guys? Bad cable? Bad connector on a cable? Anything?

Thanks again. Hope to solve this soon.

Hmm, both tuners were working fine about 2 months ago in my old house connected to a slimline directly with two cables. Guess it could have gone bad since then. Any way to check the possibility of a bad tuner? Run a second line from the dish and bypass the SWM? I am just worried that the receiver might tune fine with 2 cables directly but not with the SWM and that might not warrant a replacement unit from DirecTV.

Also of note, I only get those readings on tuner 2 when using the high freq barrel connector. When the cable is run through a DirecTV approved high freq. splitter for the SWM it does not receive any signal on tuner 2.
