Very Slow-to-show dirty picture on Samsung problemasma
I have a 50" Samsung Plasma HP-T5054. It wall wall mounted for a few years, and I recently took it down to replace it with a 65" JS9000 4K. I let it sit for a month (it heavy) before moving it to a bedroom when I found it now has a problem.
When first turning it on, I basically get a black screen with a very small but cloudy/dirty viewable area. Over time (maybe 15 minutes in the screenshots) more of the picture becomes visible, but what is visible still has that cloudy/dirty look. The picture is very dim and colors look bad as well.
