Query: TV Picture was distorted

I bought this product and it was easy to install. I have DISHTV and there was no diagram to tell you how to install it. Once I did, I noticed immediately that the TV pictures wasn't as good as before. It was grainy and had a slight flicker. I tried to get information from Sony and got only canned answers back which were non responsive. So I have repacked this item and intend to return it. Very disappointed. I may try it one more time because it does have the items I was looking for and maybe this was a defective product. I was concerned about the criticism of the product in general by the other customer but I am willing to try it one more time before switching to another company.
