I changed the inverter board but the screen is still not working!

My screen suddenly turned very dark.

The computer is on but the brightness is zero.

Right now, I can only set the brightness to 1,

it's the only way the computer stays long enough for me to work on it.

But it's annoying that I cannot see in full brightness and keeps turning dark again suddenly.

I thought the inverter board was broken, so I bought a new one and replaced it but it's still the same.

I turned off the automatic display light setting, and have tried

resetting everything but it didn't help either.

Should I change the inverter cable? or the lcd screen? or both?:(

I'm a college student, so I can't afford a new computer..:(

Please, help!

Cable first

it's cheaper, then the screen if that's not the problem.

If this answer is acceptable please return and mark it.

Good Luck,

I'm going to try connecting my laptop to the external monitor, if it works fine, then can I be sure that the cable is broken? not the lcd screen?

Was the MacBook dropped before the lightning problem started ? If so the backlight (CCF lamp) or the logic board could also be the culprit.

No, It started when I left my computer on to get some lunch..I ordered the inverter board from some web site It's older than my original inverter board. I unplugged the black cable on the left side to test it, the computer lights up but when I put it to full brigtness, it gets dark again. Do you think I bought a broken one? Should I get a refund?


I would try the external monitor before doing anything else.If it works there it could be the cable or LCD-if not you probably have a logic board problem Ralph +


I just connected to TV, it works fine. I don't think it's a logic board problem.(thank god!! :) So I should try the cable then.if not the lcd screen...

thank you all! :)
