Awesome site and awesome guide. This exteneded the life of my MacBook. I can't thank you enough!!!!

For about 3 years I had been dealing with my screen backlight shuting off. I would then dim the screen up and down until I could get it to stay. Sometimes it would work the first time other times I would be doing it for 10 minutes and other times I would give up for a few hours and come back and the screen would be on again. It would also do this sometimes when I opened the laptop at a certain angle or bumped the computer.

Well after these years very annoying behavior, my screen wont turn back on. I can see my desktop when I shine a light on the screen and hear the fan running so I know the computer works fine.

I've tried unpluging the inverter board to see if it was a loose connection, but that didn't work. I tried wiggling it around until the screen turned on and nothing.... Please help!

Is this a problem with my inverter or the inverter cable? Or the backlight cable?

What parts should I buy?

Hi, I've had the same trouble. Today I solved with a spray electronic cleaner :)

Hi everybody! Last year bought a new inverter, new cable and other stuff and replaced. Problem not solved, screen still turning black. Thinking to get a new display, but today bought spray electronic cleaner, sprayed over the display data cable (https://d3nevzfk7ii3be.cloudfront.net/ig...). Problem &&^&^$^ solved! :) Time: 15 mins, money: 5$. Good tutorial tho! :P

These are a very comprehensive set of instructions and give a really good grand tour of the innards of a MacBook 8. They are also useful for replacing the hard drive or the optical drive.

Couple of hints:

1. Have on hand some canned compressed air - the inside of a laptop is generally quite full of dust and fluff.

2. Also have on hand some contact cleaner spray (do NOT use degreasers/lubricants/anti rust sprays such as RP 7 or WD 50). Contact cleaner sprays generally only contact isopropyl alchohol. It's good to give exposed contacts a bit of a clean - even grease from fingertips can affect conductivity and hence performance. (If possible, use powder free surgical gloves).

3. Make sure you have the right tools (don't skimp - buy the tools set from iFixit). Not using the right spudger on a plug could be the cause of irreparable damage to the circuit board.
