No Backlight; replaced inverter
After posting here with concerning my MBP17 with no backlight, it was suggested that I replace the inverter board. I ordered that from iFixIt and have replaced the board but no change...still boots up with no backlight. As I mentioned earlier, I tried replacing the screen with a known working screen assembly from another model (A1151 display assembly) but same results...no backlight.
Does this mean the motherboard is the culprit?
Is this a good question?

Hi Alan, I'm having similar issues with my MBPro 17" A1212, did you solve the problem?

I gave up and decided to just use this laptop with an external monitor

The screen on my A1261 has been dim for some time (roughly half-strength), but I put up with it. About a month ago it went completely dark (though I can see the desktop by shining a flashlight at the screen).
I have tried re-setting PRAM (several times) and SMC as well. The computer works fine otherwise; I can connect to an external monitor and it displays just fine.
This seems pretty conclusively to indicate the inverter has gone bad, yes? I would think a failed fuse would have caused the screen to go dark immediately, rather than it functioning at a lower level of brightness for some time.
