C9560 has nothing to do with the backlight. No idea what is going on. Is there even a picture? Fuse blown? Short on backlight rails? Damaged connector/cable?

Sry duke let me clear this up. The unit originally worked fine.. In valley the 3d benchmarking software. The computer would just shut off out of now where.... You guys told me to replace C9560... i tried that when i reassembled the unit had no back light. Im not sure if its relevant but maybe i installed the wrong kind of capacitor... or i messed something up while reassembling the unit? Eitherway i tried troubleshooting this but i dont know where to start the issue now is i have no backlight. I tryed a new lcd no dice.

I see. Yup mis understood. There is a picture its just the backlight. I will troubleshoot the backlight rails and post some voltages soon enough.
