Hi all friends, I have a problem with this MacBook Pro 15 "which apparently suddenly stopped working. I downloaded the scheme but by measuring the tensions I can't get to grips with it. I have seen that there may be 3 or 4 defective components in these cases but I cannot determine which one it is. Can anyone help me understand what would be the primary voltages for turning on the backlight? Thanks so much
