Weird line around edge of Samsung LCD

[Eric H]

My 2008 Samsung, bought in 2011-12 for $25, replaced one capacitor and no further problems.

However, it has been developing this weird line around the edge of the screen over that last few years, it started way out at the edge and has been creeping slowly inward. It's mostly on the top and right side, a little on the left and none at the bottom, possibly because it's moving down off the screen? Or maybe it's a Cataract where the Liquid part is deteriorating around the edge? The image is fine past the line so it's not affecting the function.

The set is probably very low hours since it failed early on in it's life, I hardly use it, but when it's really in the Summer, I like to go in the bedroom, turn on the small A/C and cool down watching TV. Running the Plasma during peak hours is too expensive.

Anyone experience this? I hadn't used the set in months and it was noticeably further in than the last time I used it.
