any tho'ts?

We have Directv at home. My daughter has a receiver that is linked to my account at her apartment. I put a dish up there myself. It has suddenly crapped out and I can't figger what the problem is. She gets a few channels, but, not even locals. I've run out of ideas as to what the problem could be. I took the LNB off my dish and put it on hers and it still doesn't work, yet, I can't pick up all channels with the LNB off her dish and it loses signal quite easily. If I call Directv will they fix the problem even tho it's not on my property? I'm not under contract...been a customer since '02...and a loyal one at that. I'm more than willing to pay for the work, but, if they say no...should I just tell them to fix it or come to my house and get their crap?
