I recently took my 75" TV off the mantle. When I reinstalled the TV the entire left side was dark and cloudy, perfectly down the middle. The TV is out of warranty but only about 16 months old. I've had problems doing some of the recommended troubleshooting because I don't have the original remote. I've been trying to schedule a repair at my home but I'd like to fix it myself, if possible. As I understand it, if I need to replace something it'll likely be the same cost as the TV.
