put your thinking CAP on for this one!

Wow.. this one is hard to describe. ON my Panasonic CT34WX54J 34"
I get Pulsing bands of "static like" lines across most of my screen. Each consecutive pulse shows the groups of "static like" lines in relatively the same areas, but when the feed is present, they seem to concentrate on darker areas of the screen. The Pulsing static lines do not go over the "Menu" screen images, only in modes (Comp1-Vid-4 and my HDMI). They do not appear at all in "Blue Mode." I have unplugged everything. Turned ON. Still there. Changed my power strip. Still there. Plugged directly into my wall out let. Still there. Changed wall outlets. Still there. It looks like either outside set interference or inside the set interference, but I am at a loss.
It almost looks like the TV is picking up a continuous feed of outside interference being captured by the antenna. Totally weird and I have never seen anything like it before.

Please help I love this set, and I would hate to give it up.

That sounds like it may be a ground loop issue. The other thing that comes to mind is a power issue where noise is coming through the power cord.

get a cheap meter at radio shack and test for ground. all sorts of emf exsist via wires in walls, other people using electric device's. I remeber the days when ma would use the mixer and we would get
all sorts of interference on the old philco. sounds like you are getting similar or radio interference. we had an incedent that a marantz amp would pick up cb radio calls. ( illegal use of booster) and once lived near a cb set that my tv picked up signals. there are filters for ac lines
and are very good at stopping these types of signals. eventually you will narrow it down via rule out. one sugg.take the set to a friends
house that is in another area. ans see the result. if it continues it's the set.
