Dark screen

My MacBook has suddenly gone dark. It charges fine and the battery lights show there's charge. The screen is very dark when powered up? When I turn the brightness down fully, then go to turn it up the screen lights up for a second then goes again? I think This is a common problem?

Anyone know what I can do? Is it fixable? I've had it since 2008.


Thanks

This happened to me recently. I changed both the inverter board and the inverter power cable and I still have a dark display which would lead me to believe that the problem is with the screen itself but if that's the case wouldn't the screen be "off" not dark? If I shine a light on the screen I can see the graphics, I thought that definitely meant the screen was ok.

Hi,


I've a black macbook (serial W88150BW0P2) with pretty much the same problem.

When I start it, may be the display works with back light or not.

Then I start pressing light up/down buttons and suddenly, without any pattern and with a random times that I press light up/down buttons, backlight start to work again; still, sometimes, there's a black spot on the left side of the display.


As far as I could read in teh foruns until now, it can be the inverter or the LCD.

Can anyone help me to take the next steps?

Where can I buy an inverter? what's the reference number for the inverter I should look for?

How can it be replaced?


Best regards, in advance.

I changed both, the inverter and the inverter cable. Neither one worked which leads me to believe that it's either the display or that one of the pieces I changed were bad to begin with. I doubt it's the display because if it was it shouldn't light up at all but I'm not a supertech so I could be wrong but no one in the forum was able to answer my question.


You can find the inverter and inverter cable from either eBay or powerbookmedic.com. They are both cheap but getting to the item in the laptop is a bit of a pain in the butt especially when all the work was for nothing.


Good luck
