    Hello Everyone -

    To begin with, I own a MBP Intel Core Duo 2.0/2 Gigs of ram. I've had this laptop for roughly 18 months and do not have Applecare. I take extreme good care of all my stuff and still baby it till this day. I have NEVER bumped the laptop against anything, accidently dropped it too hard on the desk or anything similar along the lines. Essentially, looking new!

    About 2 days ago, I was working with my laptop and I closed the lid which made the computer go to sleep. Everything all normal & no appearance of anything!
    Around mid-night, I opened the MBP's lid to check my email. (Computer awakes, I can hear the Superdrive awake) then boom, a blank screen. The monitor did not turn on then burn out, it was always off. Similar to if you dim your monitor all the way. I can still see the desktop however, there is no light. If I take my flashlight and point it to the desktop, I can see everything.

    Now I need your help! I called a few places, and they described it is the Inverter board or could be the fluorescent bulb that is damaged. My reasoning for the inverter board is faulty is because when a fluorescent bulb goes out it, it tends to flicker at first. Researching this forum, I noticed most MBP users LCD's that go out, they flicker but, mine just went out and I can still see the desktop. Where can I order the inverter board? I tried but they're out of stock. I will change the inverter board myself because it will be quicker and I need to use my laptop. It is currently hooked up to an external monitor until I can get this fixed.
    I'll appreciate all the responses and thanks in advance.

    Sounds like what happened to my buddy's 2GHz Core Duo MacBook Pro. The inverter went out, he got it from PowerBookMedic, and I replaced it for him, works like a champ now.

    You might try ebay, they have a store on there that might have them.

    Try They carry all sorts of stuff. If all else fails, I bet you could just call Apple and beg them to extend the warranty for you or at least sell you the part.

    It's hard to say for sure exactly what the problem is. But, the inverter lights up the light in LCD panel. Your cheapest fix is to replace the inverter located in the LCD panel and if that doesn't work then the light is burned out in the LCD panel itself. You would be then looking at replacing LCD panel. Could also be a loose wire, but not likely.

    You can find a guide here for the macbook pro:
    There server is slow so be patient.

    Currently there is no macbook pro inverters on ebay. Interestingly, the macbook pro inverter looks just like the macbook inverter. I don't know if they are interchangeable.
    You could call Apple. I do have an spare macbook inverter.

    Powerbookmedics have a macbook pro inverter for $70 and the link is below.

    The MacBook Pro inverter is significantly different from the MacBook, trust me I have held both in my hand (I was going to put mine in my friend's MacBook Pro but they are not compatible) so... that wouldn't work.

    It has been a week or so since I have replaced the damaged part & I forgot to update this thread.
    Yes - turns out it was the inverter! It works perfectly fine, except for the fact that I scratched my pristine condition MBP while taking off the case for install. It is centimeter small but, I will order a new case because I'm an anal owner!

    Thank you to those who commented! :apple:

    dropped my macbook pro

    The exact same thing happened to me when I dropped my macbook pro. The screen was extremely dark and initially I thought it was just a black screen. Then, when holding a flashlight up to it, I could make out the entire desktop and see the mouse moving and everything. Do you think it is the inverter I need to replace? And how much did that cost you?

    Do the Apple Store/distributor repair this inverter board problem or are they going to give you a new Macbook instead if it's a brand new macbook?
