Appreciate the pictures.
A white screen almost always indicate a failed T-CON interface.
Have you checked the LVDS cables from the main board to the T-CON board? ...from the T-CON board to the screen/display?
The simplest approach would be to replace the T-CON board.
Not unless you would want a limited component level checking first.
Considering the cost of a used board from a donor TV, board replacement may be more to your advantage.
This would serve as both an attempt of a fix and as a test by process of elimination.
Please post back how you would want to approach this and/or should additional information be needed.
Please click HERE and HERE to consider / serve as basis.
Is further information/assistance still needed with this?
Appreciate the post back and an update when able.
