3rd UPDATE - PNC58C8000 Pink banding with white backgrounds
After having the plasma panel replaced under warranty in May 2012, the pink banding returned about 6 months later. After several calls to Samsung over the next few months, I finally gave up after they refused to correct the problem. I spoke to a couple different "Executive Customer Relations" representatives, but I was told they would not repair or replace my TV since it was out of warranty. I eventually found a Samsung service bulletin (#ASC20130528001) on the Chang.org website, that was published in May 2013, for the Pink Banding issue.. I called Samsung again after finding this service bulletin and they still refused to cover the problem under warranty, even though it was a well known problem. The service bulletin calls for an logic S/W upgrade and voltage adjustment. Following directions I found on a few different forums, I was able to do the software upgrade and voltage adjustment myself and the pink banding problem is gone.
I am extremely unhappy with Samsung, they have to had known there was a design issue with this family of Plasma TV's, and they should have offered to rectify the problem for me since the original problem surfaced while my TV was under warranty.
If you have this Pink Banding problem with your Samsung Plasma TV, it can be fixed in an hour or so.

Many people have reported that they have solved the Pink Banding issue only by adjusting the VS voltage to 213v, without updating the Logic S/W.
