I had directv put in around January this year and have had a few problems but like it overall. The bedroom I have a standard hd receiver and living room dvr hd receiver. The problem is always with the living room.

Around 80 days of having directv I had problems on the dvr where it said no signal on antenna 2. They came out and replaced the lnb and has been fine since till today and it is doing the same thing. I'd imagine calling them out to replace it would be a bit expensive since it is outside the 90 day repair window and I am not paying for $6 warranty stuff.

What do I need to buy to replace that part again on the front of the antenna? Also where

This was in my original install order on their website: 5LNB - SL5S

Thanks!

Call again, ask for service, tell them it's the same problem, they didn't fix it last time.

Sounds like the problem was not with the LNB itself but with the cable connection at one end or the other or with the antenna 2 tuner in the STB.
Make sure the cable is tightly connected especialy on the LNB end since in warmer weather it could loosen up due to expansion.
You might try switching the cables on the LNB end to see if it is the cable or the LNB itself?
