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?

also i plug a scart to another tv and see only snow(like no aerial signal).i press the menu on fault tv but no change.
TV Technician: Louie, Technician replied 11 months ago

I understand.

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.
