Apologies: Yet another LCD/backlight question!

Ok so the Macbook we've had since '06 is great. Its taken a pretty rough beating over the years through many hours of use (sometimes 24h+!) but is still going strong.

Except the backlight is now non existent. Always trying to find the 'sweet spot', even this doesn't work sometimes.

Is it possible to change the inverter AND cable using the method shown in this link?

I know there is the other method of dismantling the whole bottom case, but I don't want to jump into that if I don't have to.

I intend to check the cables before I attempt to replace anything, but I'm guessing it's the cable pinching on the hinges or a loose connection. If not, maybe replace the inverter cable, then try the inverter.

Thanks for this site people, It's a godsend! Keep up the good work :)
