Yep, we had a lower end LCD at work that lived on Fox Business last year. The graphics definitely burnt-in (or whatever you want to call it if it's not burn in). It still works by the way.Perhaps it is not called burn in, but I have seen this on several lower end LCD tvs in the past. Many that kept working for a long time after they developed this problem
Suprised to see it on an LG however.
