hi,
This TV sometimes shut off itself surely for some bad contact of power supply board that (for use and heat) wasn't planar anymore.
Found a same on ebay at an affordable price and compared part number and component side components was exactly the same I bought it.
The board is perfect and new and the random shut off problem disappeared but there is a dark side on the screen that isnt' present with the old board.
Take a look on the back of the newe power board I noticed that this one hasn't some components (4 resistors and 3 transistor) that made me suppose that it was the cause that some LED of backlight didnt' work.
I moved one by by one this componets from the old power board to the new one testing it, but the problem still exist so I suppose there is something else to add or maybe a bridge to move.
Actually I haven't find the power board schematic but for now I start to attach missed component pictures reference.
