Hello again Jeff. My newer t.v. has not done the pixeling lately, nor has it lost the signal altogether. I think it may have been the weather (snow & sleet) that caused it on those two occasions, plus the fact that the DISH tech said I had a weak signal somewhere. I just thought it odd for it to happen on just one t.v.
Regarding your question:

A comparison of the signal strengths on the two units (same channel like you did, but instead of looking at the picture for comparison, compare the signal strengths) will provide crucial information about your system. Let me know how much the two differ. Since the SD is your largest concern with its blurry, blotchy picture, what is your signal strength on satellite 119, transponder 11, for both units? What is your signal strength for 110, transponder 11, for both?

I don't know how to get to the transponder #'s you ask for. I know how to get to the screen with the satellite #'s, and they just all show green. At the top of this screen it says "good". When the (2nd) DISH tech came last week he only tested the t.v. that I told him had the poorest picture, and the one that was occasionally cutting out; after he did his analysis on this receiver he didn't bother with the other t.v. and receiver. Anyway, maybe this is all a waste of time until I we finally can get a DISH tech up on the roof again, as he definitely said our installation was done incorrectly and that was responsible in large part, to our poor SD reception. We had to cancel due to snow/ice on the roof and bitter cold!
Also, regarding your question about cables, the actual wiring coming into the house from the dish is
years old; we have been DISH network subscribers for at least 7 years and to my knowledge these are "original equipment". This
IS, in fact the wiring that goes to the t.v. (larger one - 50") which I feel has the poorer picture quallity. The cables from the 612 receivers to the t.v.'s are brand new on both t.v.'s and are HDMI cables. What is an LNBF(?) and do they switch these out when they install a new dish or receiver or could I have one of those that is 7-8 years old too?!

Newer generation digital receivers and televisions do such a great job of displaying the input signal for SD (or HD) picture, that everything that is out of adjustment shows up clearly as compromised picture. They very accurately display the digital picture according to the signal quality (garbage-in, garbage-out) and the quality of the television's calibration.

This gives me hope that I will receive excellent SD picture quality when this is all said and done. As I have mentioned many times in this thread the OLD receiver with the same t.v. had beautiful SD. I was afraid that maybe the newer generation HD receiver had a definite bias for HD only and I would have to just get used to nasty SD picture quality.
One other thing: You had asked me previously about viewing distance and I told you I thought maybe about 5 feet - actually my chair is located at 9 feet, dead center, and where my husband sits is 7.5 feet and approx. 30 deg. angle.
Thank you again.
