usual fix for this is a replacement of the LCD screen.
It has to be the one that is exactly the same as the existing one for it to work.
You "may" be able to replace the backlight itself but that is doubtful.
Look on ebay for replacement LCD's for your machine

Sometimes this machine works perfectly. More & more frequently the screen starts to shimmer, then goes dark. It's not off, because I can see a faint image of the screen, but it's very faint & dark. Sometimes by closing & re-opening screen it will come back to life. Sometimes increasing the brightness with the brightness key will cause the dark condition to occur. I'm very capable of repairing what needs to be done if I only knew what to do. TD
