No backlight on screen but LCD OK
Hi,
I very recently bought a 2013 macbook pro retina 15 serial number C02LPBG2FD56. I bought it as faulty with no display backlight.
The LCD is working as I checked it with a torch through the Apple logo. I believe it has suffer a small amount of liquid damage as one of the warning indicators is red. One on the other side is still white.
I have tested the F9700 fuse with a multimeter and there is no continuity. For a moment, I thought I had found the fault but I started testing other similar looking components close by the blown fuse. I did not get continuity from some of these other components. Everything looks normal to me but I am no expert. Bearing in mind that my knowledge at this level, is very hit and miss.
Where do I check next after proving the F9700 has blown?
Thanks in advance....ritchy
Check the pins on your LCD connector for corrosion or otherwise damaged. You also want to make sure that there is no short circuit within that connector.
