Chosen Solution

MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Troubleshooting Hi, Recently, an accident caused a huge crack on my MacBook Pro 15" A1260. I got the parts, and followed the instructions in the repair manual to replace the screen. However, once I finished the replacement, it appeared that the backlight is not working. I’m sure the LCD panel works, because if I look really closely at the screen, I can see my desktop/finder/icons, I can even see the change in brightness when I push the button. Before the replacement, everything but the screen worked fine. Thanks

Usually if you can see the desktop but the screen is dark, the inverter has failed or the cabling to it is damaged. Here’s the part: MacBook Pro 15" (Models A1226/A1260) LED Driver Board Here’s how to replace it: MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Rear Display Bezel Replacement
