Yellow Blobs & ECO Saving
I had "yellow blobs" on both sides and very obvious, but now I can just barely notice the one on the right hand side. I turned on ECO/Energy saving several weeks back and immediately noticed a reduction in the blobs. And it has continued to get better... or less noticeable. This may sound like heresy, but I also think the picture quality is much better with ECO/Energy saving turned on. The picture has more depth and blacks are blacker. Yeah, it's not as bright but plasmas are not suppose to be overly bright. I think the energy saving mode allows the plasma phosphors to perform within normal parameters and it has allowed my TV to basically heal itself. In addition, I no longer hear any buzzing. Give it a try.
