OK - Pic is not really clear enough - needs to be taken in more light.
What is the number on top of the grey rectangles with yellow stripe
(inverter transformers) marked in your picture.
On the right near the connector is that a torpedo fuse - can you check it.
Do you have a multimeter and soldering equipment.
What is the part number of the board?
Do you know what was replaced under warranty?

White screen because the Video signal cable
to the panel is not connected or seated correctly?

Are the two backlight transformers
secondary windings equal to each other
in resistance?

That is an inverter it should have a L*** number on the board beside it.
They rarely go bad and when they do they burn up.
What is the part number I asked for? It is marked in yellow on your first picture
