I don't want to make a new thread so I post it in here hopefully to get some help.
I got the pn59d550 about a month ago. I was initially looking for LED but after lot of research, I decide to go plasma since the picture quality / price ratio. I also read the problem of image retention is the pass.
I didn't do the breaking in, just using my TV with my HD Over the air antenna for a couple of hours and then switch to PC (HDMI) mode.
I was using it for a couple of hours. The next day, I found out that image retention is there. "Youtube" logo was visible, also a dark bar on top (lot of website use this design). I was stupid to use the dynamic preset. I cranked up the settings so much.
I did not panic, I reassure myself that a couple of intense TV, BD use will erase those marks.
Well, the logo went away after a couple of hours or a day (not visible anymore). However the bar is still there.
It's now over 2 weeks since and I use TV for 4-5 hours a day. I ran the build in gray slide, break in slides (simple color pictures) etc.. The bar is getting lighter but still visible. The problem is once you see those marks, you see them whenever the TV is on.
The bar is only visible with a white or bright background. On colored scene, it's not visible at all.
Now I am a little worry that it will stay there forever
I love this TV. I owned LCD before and they're not nearly comparable in term of picture quality.
What can I do to get rid of it ? Should I call Samsung support for help or try to get any warranty out of it ?
