Just so others with more expertise can help you, are you saying that the screen is just a blank blue screen or that you gat the normal image, but in just a blue colour?

It is a solid blue screen,

So there is no image at all, just a blue screen, like in some LCD test?
In this case, first step is to try a known good assembly LCD + video cable.

I have already tested a known working LCD and i just got the blue screen, solid blue

Check for knocked off components on DATA lines of J9000.
Also check resistance to ground on all these lines...
