It is NOT a problem with the backlight since you can see the backlight moving when you move the magic remote.

I might try a heat gun gently to the driver chips on the ribbon, but I doubt that will work. I've seen several other posts about this same issue, but no one has really tried to go to the depth I did. The repair shop even said I've basically tried everything that can be done.
