I've had the TV for a couple years and it's no longer under warranty. Over the last year I've experienced this issue about 8 times and it can last anywhere from 5 minutes to a week. The last time was about a week ago and it hasn't got better.
The issue: The screen will get extremely dark (almost a dark red sometimes) and will flicker on occasion as if it's trying to fix itself. Sometimes when I change the picture settings and view mode it will help bring it back. It happens on all inputs, netflix, and even the TV menu can be tough to see when having problems.
Thoughts on a fix? should I take it off the wall and check connections, etc? Your help or thoughts are greatly appreciated!
