Hi As Q stated why the screen of death Blue oR Red not pink or other color and what exactly cause screen to show like blank colour? Is it SDA line from processor

I’m not sure anyone in the repair community has ever bothered to understand “why” it’s one colour over the other. Remember that LCD’s work because each pixel has three sub-pixels in Red/Green/Blue. Presumably whatever cause the failure only lights up one of those sub-pixels, hence the red or blue screens of death.
