My backlight will shut off. It is just the backlight, if I shine a light near the screen I can still see the image. If I turn the tv off and back on, it will work properly for maybe 30 seconds. The longer the TV is left off, the longer it will work when turned back on.
Did a search, seems like this could be the same issue as mine:

Post hadn't been updated in a while, thought it would be better to start a new topic.
The back of the set near the power board (model PLHL-T722A) gets unusually warm, although honestly it wasn't something I would have checked before I had problems. Maybe it was always like that. Also, there is a slight toasty smell coming from the vent over the power board.
I removed the back of the set, and was hoping to see some bulging capacitors (had fixed a different tv previously by replacing them). All the capacitors on the power board look ok. All flat tops except the very large black capacitors in the center of the board. They are black on top, no vents... maybe they aren't capacitors. Are these supposed to be completely flat also? When I look at pictures of the board online, they all seem to have a slight arc to them.
The only spot on the board that looked like potential trouble was on the back of the board. This is near where the backlight(s) plug in. I attached an image, look about an inch to the left of the white peg. Maybe that is just flux? Difficult to tell from the image, sorry for the poor quality.
There was a firmware update that mentions this issue specifically, but it didn't help. It is the actual hardware, not the software.
Any suggestions? I would like to confirm it is the power board before I replace it.
