Samsung 58" C7000 Plasma (sold as C8000 in the states I believe)
Has what's called the 'pink screen/band of death'.
It started out as a small .5 inch pink band in the top right of the screen. Over time the band is now 3-5 inch right across the top and also occurs halfway down the panel.
It's most noticeable on white/light backgrounds. When I use the TV as a monitor the banding would come and go when either scrolling or panning when gaming etc.
It started when the panel was about 13 months old.
It also sporadically buzzes very loudly in the bottom right hand corner of the screen - mostly when using a HDMI input.
I've been meaning to get it looked at under the extended warranty, but with more pressing R/L matters and not being able to find the receipt/documentation - I've just put up with it.
I am familiar with it. You will need a new plasma panel. The servicer might try to replace the Y Main, X Main, even the Logic or Main board, but my experience has been 100% a panel replacement is the only fix. Even though it may be hard to see, put on the screen burn scrolling function. Also go to the support section of menu, and self diagnostics, pull up the picture test. Again, it may be harder to see, but should also show there.
This is not diffusion (red sparkles throughout), that can sometimes be adjusted out. But rather a reddish/pinkish "rash". It would be very obvious on a total white screen (possible for you if you save a white image to a USB and view it on the set).
Depending on the servicers walking orders from the extended warranty company (IE: keep the repair as cheap as possible, order only 1 part at a time, etc.), they may want to try parts (mentioned above). But I will wager it will require a panel replacement in the end.

P.S. If the sporadic buzzing is from the actual TV, and not through the speaker, then likely the panel replacement will fix both issues. The buzzing could be a drive board buzzing with certain picture content.
