So i have had this tv from new for over 5 years. Never had a problem with it until now. It started about a year ago. The back light will random dim and stay start just enough to see that there is a picture but can't watch any thing. If u go in to the product menu and reset the tv to new and reset every part. It used to be only once every 2 months now it's 2 times a night some times. I have updated the tv with the new software. I just got the new sony 950b but i don't want to let this tv go yet. What does the back light do or act like when it gets old and dying? It's a non led model. Thank u for all the help.
