775 error on new / old set up, bad LNB?

Just moved into a new rent house and trying to get my sat up and running. The dish from the previous house belongs to the owner, so I couldn't take it with me. At this house it appears to have the same dish sl3-swm. I say this because there is only one wire dropped from the roof, a four way splitter in the box and it doest look like a 5. I re-terminated all connections after first set up didn't work, yes, they're properly done. I had to make extensions from the house lines to the the splitter, spectrum cut them short on their install. I used a scout 3 to ensure I had the proper cables hooked up. 

I have tried multiple ways of setting this up. Pwr to swm in dc pass with terminator on pwr to ird, and terminators on the two ends I wasn't using yet.

Pwr to swm to the lnb and pwr to ird feeding the splitter. 

Pwr to swm feeding the lnb and pwr to ird to the receiver

I have h25 receivers, all grounds look good.

Anything I'm missing?

Haven't been up to the dish yet, have a buddy coming with an extension ladder this weekend, my 10ft won't get me on the roof here. I ordered a sl5—swm and new four way splitter, but to not waste time with my buddy, is there anything I'm missing? Should I get a new drop line too? I have used rg6q for everything I have done. I have enough left to make the line, can I steal the ground off of the one that is up there?

Thanks in advance!
