Well, I opened the back cover and as you can see in the picture, I unplugged 2 L (left) ribbon, TV turned ON, but half of screen (Right) is normal, and the other side (Left) is white. i continued to test...
Result:
I swapped the ribbons L<-->R = Blinking 2x power light, 5x timer light
Unplugged 2 R Plug 2 L = Blinking 2x power light, 5x timer light
Unplugged 2 L Plug 2 R = Blinking 2x power light, 5x timer light

Only in the first test, where I did not change the ribbons, when I unplugged 2 ribbons on the left, half of the image is normal, and the other side (unplugged side) is white.

Does anyone have any solution?
