my guess its the "standard panel / tab" issue. The tabs on one side are causing issues. They can be removed and the set will operate normally in a "saved" fashion.
No, I understood. I've read the long thread on the 70" vizio but it seems in the past week there have been two posts now saying that that fix finally didn't last.
I also have played with a 70" vizio a few weeks ago and performed the repair however in my panel, I think the owner had run the set for hours and hours with the panel being bad and may have affected both sides. When we first got the set we had the classic no picture. And after removing the tabs on one of the sides we had picture but very poor quality. It isin't always a slam dunk, but a fun project for sure. If you don't have a spare $100 to loose then I wouldn't do it due to risk but if you do it is worth it.
