Don't quote me on this, as I am no expert, but it sounds like the "floating blacks" issue reported by the CNet review.
Quoting from CNet:
"Blacks and dark areas of the picture, as we have come to expect from Panasonic plasmas over the years, are deep and rich. However, the set floats black
, which means blacks pump or fluctuate slightly, becoming darker or lighter depending on how much bright content is in a given scene."
Since you report these lighter "blobs" appear in the dark areas when there are other bright areas on screen, I think that's what you are seeing. I believe it has something to do with the "dynamic contrast enhancement" feature of the plasma or something. At this point, you have officially exceeding my technical knowledge of the subject
Check if the CATS option is turned "ON" in the Picture menu, I believe this settings ups the "dynamic contrast" boost and turning if off may help...
