So me and my mom went to Target and saw a Tv on sale for about $250 so we bought it was 43 inches and we got home plugged it up and it had a little bit of a foggy tint in one area of the screen. It now has a foggy layer over the whole screen and we can not find a fix for the tv screen.
@kaidenjohnson fog, haziness etc. is usually an issue with the Gamma IC on the T-con board. The strange thing here is that you said it started on a specific area of the screen so there is a possibility that this is a bad panel. I would try a new T-con board and then re-evaluate.
