I have isolated this as follows: the Sharp LCD monitor and the H20 receiver are plugged into the same outlet. And only the three video (Y Pb Pr) cables connect the two devices together. (Of course there is also a single cable going out to the LNB array.) No other connections.
The problem is not seen when a different Y Pb Pr source is plugged into the Sharp monitor. And the problem *is* seen when connect the H20 output to a different display.
It is intermittant - sometimes for hours the degradation will be there and at other times it is not noticable. I suspect (especially noting the heat generated by this box) that there may be something in the H20 that is failing - possibly some caps or other component(s) making internal ground loops?
The composite (yellow RCA) output does NOT exhibit the problem; I have yet to get an HDMI cable connected between these units to see if the issue is evident with that method of connection.
"Not to sound like a broken record" [yeah I know few may remember them].
I doubt there is anything failing in your H20. Since you say it "comes and goes", I'd look to see what is changing in your house [A/C on/off? etc.]
Your SAT feed should be grounded and "I think" the H20 has a three prong plug too. [both of mine are stowed away so I can't just go see].
"I'd bet" your other equipment isn't using 3 prong plugs.
Again, we just when through this on the other forum, and had everybody "chime in", most of which just "clouded" the issue. "In this case" it was with a recorder so the SAT cables could be removed while watching a recording. This "proved" the HR was the ground of "the loop" and with some detective work the op was able to walk around the house and switch off everything [well I think he went to the power panel and switched off/on breakers] and then went one by one until he found "the heater". He had two [same model] and "one did and one didn't". "It seems" one had a miss-wired capacitor on the thermostat, which put "noise" [voltage] on the neutral line than was going to ground through the TV to HR to SAT feed.
