Backlighting issue

Please help. MacBook (Blackbook) with failing backlight. Screen is dark when in certain positions. Wasn't too bad at first, fiddling around with display (opening and closing, or raising and lowering the display) has worked so far, now it's getting bad and unpredictable. No apple stores in my state. Apple representatives here charge 139.99 just to take a look, then extra 59.99 per hour after. No money. :(
I read on forums that it might be an inverter cable, but guides are less then easy to follow.
Specs: 2.2 GHz Intel Core 2 Due, running OS X 10.7.4. Bought in October 2008.

Question: would opening up case and messing around with wire / cable help? Is it possible that wires are being pinched? Are there any guides that start from the beginning to end, and not start as if I knew how to properly remove keyboard without assistance? If need replacements, link? Thanks!

Ifixit can get you started but the parts. cable, inverter board, and possible screen backlight are going to cost like sin.

Apple has a flat rate repair but its up in the $250 range.

The repair is stating to exceed the value of the machine.

^^^IFixit is good.

Before you open it up make sure you can still get a signal on an external monitor so that you will still have access to your working computer and data, etc.

These things take a lot of disassembly even to change a hard drive so be prepared for it.

That $139 will buy you an aftermarket screen, inverter and inverter cable. I just replaced my screen (only) on my Blackbook because the backlight wouldn't stay on. Found compatible screen on Amazon for $92 bucks and replaced it myself within an hour after watching a how to vid on YT. Works like new once again. Not saying thats the problem your having, but at that price its worth a shot.
