    About a week ago I was using my Macbook just fine and then i closed the lid like normal after finishing. I went back to it 30 minutes later, opened it and the screen was dark but could still see the desktop (as if the brightness setting was on 0). I fiddled with it for a bit and found that if I put the brightness down to 0 then back up, the screen would come on for a few seconds and then go off. I left it for a day, tried again and the same. I then put a bit of pressure on the bottom right corner, as if pushing the screen towards the keyboard, put the brightness down and then up and the screen worked again. I could move the laptop, screen etc and it stayed on. I then closed it, opened it and back to square one.

    It works very randomly. I'm using it now but it might well go off in the next 5 minutes. Also, the volume wasn't working until i shut the computer down, started it again and held D down. It worked first time then.

    My question is, does this sound like an inverter cable problem, or will it be the inverter board? I was told it might be the tubes in the screen which would require i new screen but as i've been using it now for 15 minutes like normal, i dont think it is that.

    Sorry for the long description but i like to be detailed.

    Any help would be much apprecaited.

    From what you have described it certainly sounds like an issue with the inverter board. It sounds unlikely to be a failing Lcd display. What macbook do you have? I know that failing inverter boards are a common problem in pre unibody (2006 - 2008 & mid 09) white MacBooks, but this is not the case with the unibody models. depending on which macbook you have, changing the inverter board is a relatively straightforward task and should take no longer than 10 mins to replace. it's also a fairly inexpensive part and is readily available.
