I just had a 522 receiver installed yesterday (replaced an old 501). Everything is great except I have REALLY bad picture quality/resolution on TV2, which is an RCA 15L500TD. The installer was very helpful and tried everything; when he called they said it had something to do with the tv thinking the dbs signal was illegal so it was preventing it from showing. He tried using coax and rca connections, and also tested using the 501 receiver to rule that out. We tested the tv using a cable connection in my son's room and it worked fine. Also brought an older tv to the TV2 connection and it worked fine. Seems to be just this particular tv. Anyone ever heard of this? Is there anything else I can do/try? Thanks!
