To be honest, there;s not much you can do. I've tried all of the suggestions that have been posted in this forum and nothing really works well. As a result, I will be replacing my set with a new D8000 plasma.
It's been years since I've posted anything on the forums but my issue with my Samsung is driving me crazy:
I have a really really bad HALO effect on ALL sources, including Blu Ray, and it doesn't matter which movie it is, there's a terrible pixelated ring around moving objects, mostly people.
I've tried the few suggestions made earlier in this thread with no luck, and I've also calibrated it different ways from the calibration thread.
I have the very first rollout of this set so that might be it. I don't remember seeing it when I first got the set so I'm wondering if it was the result of a firmware update. Is that possible??
Any suggestions would be great. My way older Sony has absolutely no problems like this.
