LCD NO Backlight - Extra Monitor Works FINE - Backlight Randomly Shine

History

NEED FOR SURE ANSWER IF POSSIBLE : )

My MBO was working just fine had fan noise then then went to sleep mode then when I attempted to wake it up the backlight was fully off i reseted everything sometimes randomly the screen lights up for a few seconds then back off but once in a blue moon.

What can this be? It works with external monitor just fine keyboard lights up and all.

I CAN SEE with a flashlight sideways everything just fine but no backlight.

What can i test / check to see what the issue may be?

THANKS : )

I am experiencing the same issue, however i just replaced the inverter, and my i sight and my keyboard led is working just fine, this is becoming very frustrating... not sure where to go from here Thanks

lbrockbank,

are you sure about the connectors/wires? are you sure your left IO board produces correct voltage? https://d3nevzfk7ii3be.cloudfront.net/ig...

Serjio,

Since you can see the the desktop dimly your most probable failure is the LED driver board. Here's how to replace it, but check your connections first: MacBook Pro 15" Core 2 Duo Models A1226 and A1260 LED Driver Board Replacement
