I bought a late 2011 MacBook pro for parts. The computer turns on and functions but there is no lcd backlight. I can see there is video to the screen when shining a light through the back of the apple logo.
The lvds connector looks fine. The motherboard looks good. I've tried an SMC and a PRAM reset but those have failed.
I've heard that backlight fuses go bad but I don't have the right soldering iron, or confidence, to replace the fuse.
I see another board beneath the LCD clutchplate. Is that board an inverter? If so, maybe the inverter is the cause of the problem?
I have a couple mid 2010 mbp lcd assemblies sitting around but it appears those have a different cable layout. Before I try to dismantle these LCDs to find any cross-over parts, does anyone know if the 2010 mbp LCDs are compatible with a late 2011 board?
What do you suggest trying next? How can I isolate this problem?
