Why is my power board burning?
I’ve had my Vizio model M471i-a2 for about 4 years, and about a week ago it started emitting a strong burning smell, and then the top of the screen started having Black flickerings. Took off the back and saw a substantial burn mark on the power board.
Ordered a new board and put the new one in Saturday. Now (Monday night) the same thing is happening all over again to the brand new board!

Did you try connecting power through a different outlet?

I have the same problem, did anyone find a solution for this?

Hey dude, it did end up being my LED backlights. I wish I would have known that before purchasing new boards, as it will just burn through any new board you install.

I have this same issue on the same model tv. Same burn marks on same board. Do I need to replace the backlights and the board or just the backlights?
