MacBook Pro A1707 No backlight - GSM-Forum

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

check for shorts on backlight coil....if no and volt is 50v around... it is probably LCD backlight flex. known as FLEXGATE... and it is fixable.
